If you need to add custom unique identifiers to your form entries, you can use the Unique ID widget. Unlike Random Value Generator, Unique ID is not visible on the form and only generates unique IDs after submission, making it faster and ideal for high-traffic forms.
To set up Unique ID
- In the Form Builder, select Add Form Elements in the upper-left corner.
- In Form Elements on the left, go to Widgets at the top.
- Search and select Unique ID.

- Set your configurations in the properties pane on the right.
Note: To open properties, select the widget’s gear icon.

Note
The Sequential Numbers ID generation method increases the ID numbers by an increment of one from Current Index regardless of previous entries. Setting Current Index to a number lower than its current value may result in duplicate IDs.
Here are the available options:
- Prefix — Add a string in front of the IDs.
- Unique ID Generation Method:
- Sequential Numbers — Use an auto-incrementing number as IDs for your entries.
- Current Index — The sequential ID number’s current position. See note.
- Number of Digits — Set your IDs to a fixed number of digits by prepending zeroes before the IDs.
- Random Values — Generate random IDs for your entries.
- Number of Characters — The length of the ID string.
Note: Too many characters can affect performance. The recommended number of characters is 6 to 18. - Include Character(s) — The character pool for the IDs.
- Number of Characters — The length of the ID string.
- Sequential Numbers — Use an auto-incrementing number as IDs for your entries.

Puedo crear un QR con el ID único?
The problem is I need from 1 to 6 unique ID / based on the selection done by the user for every submission.
So the unique id is ok to identify the user but I need to build&add a secondo part of this code that identifies the items, a range from 1 to 6, related to the user.
Now I split the codes in two field, the unique id plus a talking code, but this is a workaround with some limitations. The best for me is a unique code for every items in a specific field, 1/to/6
Necesito que el ID se muestre en el formulario, como puedo hacerlo
Hi. i dont want the unique ID to be hidden i want it to be shown on the pdf is this possible
Is there any way of ensuring that this unique custom ID appears on excel exports - at the moment when I attempt to export it just says 'unique ID' rather than the actual ID
Could you please clarify whether the IDs are incremented when a user begins the form, or when their response is submitted? Right now, we seem to have a situation where if user A starts the form, and then user B starts it before user A has submitted, they both receive the same ID when using the "Sequential Numbers" method.
Question Regarding a unique id.
How do i add a unique id to a form each time its submitted.
Lets say i have a list of numbers could be like this: 2019-90/35-4947, 2020-90/47-6605, 2020-90/47-7080, etc. (random and in no particulary order)
But I want each submitted form, to pick a unique number from this list. Never useing the same number twice, and in the end I should be ending up with a list that is empty.
Limiting the amount of times a form can be used by the amount of numbers in this text file each seperated by a , when its empty the submit button does not work as its required for a submit.
And it does not have to be a txt file i could be a table aswell i guess. If that would make it possible, how would this be possible within jotform?
I can't get the value of the Unique ID to be converted to a QR code, how can I do it? I am using the "dynamic QR code" widget
Is there a way to pass the number generated by this widget to another form using the prefill option with approvals? I'm trying to have 1 form generate the number, and then have that number prefilled in on another form, but it appears this widget doesn't work w/ the prefill capabilities?
We are a patient foundation and when a person signs up for one of our projects they have to fill in different forms. What we would like is for each of these people to have a different ID and that would be the way to identify them in the forms they fill in. Is this possible? Thank you
Is there a way to use the unique ID so that participants can obtain their unique ID after submission of a baseline survey and then use the Unique ID again in a follow up survey?
My customer is able to see the Unique ID. Can you advise how this is enabled cos the Unique ID is not supposed to be noticed by the audience or customer?
Hi! I was looking at the Unique ID widget as a way to identify our unique members within our non-profit organization. Members currently register using our JotForm. My question is; once a unique ID is given to their member record, is there a way that we can use that unique ID to incorporate into a different Jotform allowing that person to use that ID number to gain access to "member price discounts"? I saw that there is a way to establish subfolders using those ID's. If you set up a sub-folder with all the unique ID's can those be used to pull from to verify the member status? Hope that makes sense! Thanks in advance.
Hi! I want to show the people what random numbers they get after they submit.

Is there a way to link a person to a unique ID and the unique ID is associated and used for that person every time the person logs in?
Is there a way to have this information pulled through into the Jotform Tables?
I've tried creating a new column and connecting it up but nothing seems to pull through.
How can I make the Unique ID appear to the user? I want them to be able to see the unique ID and copy it to use in my website.
Am looking for a mechanism that when users visit my website and submit a form, they should receive a confirmation email with a unique QR code so that they can present that QR code to my office in order to get an Item. The user database will be saved on Spreadsheet.
Is there a way to enlist the sequential unique id number only if a certain field is selected? A condition to only allow the sequential number to be used if a certain condition is met?
Is there a way for certificate verification? I have my training certificates that I issue to my students generated with an ID.
Now, if someone types the ID, then details like Name, Course Undertaken, Grade appear.
In other words, there is a search tab that inputs ID.
Based on the ID, details of students appear.
Only after entering ID, details of students can be accessed.
I want to create an online form so that each person who registers either selects or is assigned a personal identifier, and allows others to search for them by this number. I also want others to see what is on their public form, but hide their email. The email would be an embedded link where the person would receive a message like "You've received a Gift."
Additionally, I want the identifier to stay with them through their purchases. For example, if a person clicks a link from my page to a vendor, then purchases something from that vendor, so that I get credit for that purchase. Is this possible?
how to create USER ID by adding the first 4 characters of firstname + last 4 digits of IC number or Phone Number
I love the number system but is there a way it can be shown after each person submits? For example, if I have 200 people filling this application. The first person to finish it will get a 0000 number and the next person 0001 and so on. I would like for Jotform to automatically generate the numbers for each person that fills out the form I'm creating.
Como hago el campo visible? ya que en avanzado no muestra la opcion.
We have issued unique booking references to customers and would like them to include them on their form submission to avoid duplications. Is this possible, or is it only possible to restrict further submissions by cookie and IP address detail?
I find the unique ID widget very disappointing. I cannot put the unique ID on my PDFs. I cannot use it as a unique identifier for Save&Continue. I cannot feed it into another field and then pipe that field onto other forms.
For us - we are trying to send Jotform documents to Docusign for legal signature. A unique ID would be very helpful for matching the docusign output to the Jotform PDF output. but we cannot do this. Is there any other way to create a completely unique ID so that forms do not get mixed up?
CAN WE ARRANGE UNIQUE ID AS PER FIELD OPTION IN IT
I have converted the jotform from the pdf fillable form, however, when I creat a unique ID onto the jotform, it will not link to the original PDF form. is there a wasy to do it?
Is there a way to have the unique ID go up when someone does an edit to their original submission and then submits the form again? I need a way to have the "edits" become a unique form entry. Thanks!
I created the Unique ID and still get an error message that says "Order ID is missing from the form submission" via mobile submission. I do not get an error message via laptop. Help! What am I doing wrong?
My form's unique ID increments such as 3 to 5 to 7 to 9.. etc
is there any way to change this back to incrementing from just by 1?
Unique ID doesn't appear for me either like NJEnrollment said back in Janurary. I'm not sure why it doesn't show up under Widgets
If i have 'n' unique fields in a form depending on the 'n' number of tickets chosen by the one who is registering can i increment the starting value for the subsequent unique fields
Serial numbers are great. But what we really need is a hash code that can't easily be guessed. For instance, a unique hash based on date and time and user input details, and that the user receives as a unique code to request some information etc in the future.
I had considered a code based on date/time and user email, for instance, but that would be pretty guessable. Even if I create an algorithm in the background that performs multiplications and substitutions that can still be decrypted.
Random numbers don't help: there's a chance to entries get the same number.
An MD5 hash or something in those lines would be awesome.
Is there any way to have the unique ID show on the form that is emailed to the submitter?
Thanks!
Brilliant!
Thanks
I can no longer find this widget as an option in the form elements.
Thanks - that was very helpful!
Cheers
Hello - is there a way to change the unique ID based on an answer to a form questions? For instance if some one chooses 6th grade I would like the number to start with a 6, etc.
Thanks!
Susan
Thankyou was really helpful
is there a way to put the unique id number added to the spreadsheet attached to the form.
Is there a way to show this number to he customer on screen at time of submitting ?
Is there a way to only have the Unique ID increment if a certain criteria is met instead of always incrementing on every submission? Thanks!
Is there a way to install this plugin and attribute an ID even to the ancient submission or does it only starts with the submissions after the plugin is installed?
tks
Alguien sabe porque no me aparece visible el campo de Unique ID en mi formulario.? lo agrego y veo que todo esta bien.. pero no lo logro hacer visible al momento de nuevos envios.
how do i let users of the form see the unique id on the form as well as i do on the submission page
Hi,
Great info. I learned a lot of things.
Thanks
Thanks for posting useful info
There is an option to be visible on the form or read-only ?
Might it be possible for this number to show in the "Thank you" message pop-up after a form is submitted? This could be useful for clients, so that they can refer back to their form number when submitting further inquiries.
If the submission is submitted to box, does it also get sent to jotforms servers? We have some strict data privacy policies internally and need to understand everywhere that our data gets sent to
What is the html code that I should use (in the source code) in order to make the unique ID show up on the form? I have been able to make it show up, but then it was not unique, it was the same number every time, while the numbers that I received by email were increasing.
I want the customer to see the unique ID and then use it as an order number in the communication with me.
So, they need to see the unique ID and I need to receive it in my email so I can connect the details that were filled out in the form with the customer that is contacting me (or depositing me money in my account)
Please give the solution to my question. I would be greatly appreciate if you reply asap.
Thank you
ajaypal
can we add in the date to the unique ID? For example.
Unique ID - DATE - {User input capture from a text box in the form}
Brilliant that you
Is there a way to change the prefix based on a required field answer? For example, our Product Category field has nine possible answers and we would like to use a 2-digit prefix based on which Product Category is selected.
Or would it be easier to assign the 2-digit code to a new field based on the Category selection and append the Unique ID, thus creating a third field?
Is there a way of using the Unique ID in a calculation and a way of showing the Unique ID on the form?

i want this unique number to appear to the user in the thank you page how can i do this ?
Só pode acrescentar 1 deses IDs, gostaria muito que você desenvolvese um comparador de numeros e letrar com traços como se fosse uma chave serial de tivação do tipo:
EDR-GDT-OPI-FGR (em letras)
e
123-4322-546-768 (em números)
ou
RT4-TE3-GH6-43J-43K (em letras e números)
por favor crie um com esses aspectos
Hi, I wanna see the unique ID when I'm filling my form, after I use the source code I cant modify directly in the same field, I copied all the code in notepad and modified, but now how can I put in my JoitForm to see the unique ID.

I want to add jotform to my email so that i can get notification when someon sent me mail.
thanks Jotform for this integration. very excited about this!
impressive!
OMG, JotForms has not only helped with me realize I was married for the last 11 years, I can now start to use BOX instead of the 30 + external drives I have???
It will be good to do the same with MEGA ()
50GB for free, no limits, very fast!
Yes! Thank you! Now I don't need to set it up through a mutli-step process with IFTTT and other automation services. You made my day!
Excellent work guys! Keep it up!
Very excited about this and it works perfectly! Thanks, Jotform!!
Is there any way that a Unique ID could have an option to not be hidden during the form submission? I can always look it up when I'm done, but this would save me time in some cases when I'm using a form for internal use within my company only.
when I try to add a unique ID I get this message You cannot add more than one Unique ID. Please delete the existing one first. but I cannot find the existing field and it is not showing up as an option in grid reports
I am using the last 4 digits of the provided phone field as the Unique ID. So far, the user needs to imput the last 4 digits in a separate field. Would it be possible to have an hidden field with a code to collect the last 4 digits of the provided phone number? Thanks in advance.
Is it possible to display this field on the form?
Is there a way to make this Unique ID get pushed to Authorize.net as the Transaction ID? Auth.net is expecting a value there. Tanks for your help! Oh so close!
is it possible to have multiples of one ID. Example: if the Primary registree has a guest or many guests (family members) whoes info I need to tie together.
I would think i might look like this: 10000-1, 10000-2, 10000-3
Thanks for your help
Hi, I have a question, I placed a unique ID on my form and I understand that it is sequential. However, when I checked the submissions, I found out that the Unique ID skipped No. 7, so now I have 1-6, then 8. How do I go about this? Thanks!
Hey Wayne,
Thanks for getting back to me. Nice homework in researching my e-mail domain, unfortunately I am creating these forms for a different domain and am not sure that your solution will work and I'm still trying to figure out the workflow.
I think I can describe hopefully a more "doable" situation for what I need and would love your guidance and help.
1. Restaurant selects their Restaurant Name and/or Review Event Date from a drop down and then enters their e-mail to receive the password for the Response Form. (I guess a separate Submit form needs to be created)
2. An e-mail is then sent to them from the Submit form with info on how to open the Restaurant Response form.
3. On my website I would like them to enter the password received AND/or the Unique ID which would then bring up BOTH the completed Review Form and the Restaurant Response Form. (ultimate wish is to present both the completed Review Form & Restaurant Response Form side-by-side) This would allow them to respond to what was actually reviewed without having to flip back & forth between either two web pages or their e-mail & the Response Form.
Any help would be greatly appreciated, along with simple (very simple please) step-by-step instructions!
THX Again!
Jerry
Question concerning the Unique ID?
1. I have created a review form with a Unique ID.
2. I have created a Response form for the "Reviewee" to respond to the inital review.
3. I would like to "link" or somehow attach the Response Form to the initial Review so that the Responder can see what they are responding to while completing their Response form. Hopefully you can follow that!
Please be gentle, I did search the forum for a similar question/answer but did not find one or did NOT understand if I did find it!
Thx for your help!
Great feature! Could you possibly add a feature to allow each ID to be randomly generated (of a length determined by the user) instead of always being consecutive numbers increasing by one?
LOVE this feature! We are so thankful for your service. You have obviously put in a LOT of hard work and it shows and has definitely paid off! Thank you!
Can you just make a Unique Submission ID for me?
For example:
-Allow me to start with a letter or number
-Able to pick how many letters then how many numbers then how many letters then how many ....
-Ability to limit ID's entire length (e.g. 6 characters max)
-Ability to be unique to just that form or to all of my Jotform forms for each user account or unique to ALL users' accounts
I'd REALLY appreciate it. Thanks. :)
Wahoo!
Unique ID changes during an EDIT, which means it is not truly Unique... At least not for most needs......
I can't get the unique id to display in the subject field of the email alert?? just comes up blank - any ideas?
ขอบคุณสำหรับสิ่งดีๆที่ใช้ง่ายและสะดวกขึ้น
You're almost out of space! ???
