How To Create Unique Identity Numbers in Kobotoolbox For Respondents

The importance of Unique Identity Number cannot be overstated. A unique number, is an identifier that marks that particular record of respondent or user as unique from every other. It allows the record to be referenced in the Summon Index without confusion or unintentional overwriting from other records. For Example, you want to generate unique number for your customers, you can use this simple logic in Kobotoolbox to generate the Identity Numbers.
This method works on both mobile and web. It uses a calculation function to create a unique serial number based on the date and time to the first millisecond. Although this method may not meet all your needs, it should give you an illustration of how much you can stretch calculate functions.

@@oluwaseunogunmolu okay, great! That'll be very helpful... Thanks

[@obedatsu-ofori7743]

thank you

[@nijaradeka5358]

This is extremely helpful for me . I have confusion. My survey will go simultaneously by different enumerator in different places. So in that case also the unique id will remain unique right????

[@oluwaseunogunmolu]

Yes, you can use unique number based on the province or state or local government. For Example, New Delhi can be Del-1234, mumbai can be Mum-1234, etc

I have learnt a lot from your content.
I have succeded in creating the unique 🆔 for my respondents. But when I go back to review the survey before submission, the unique 🆔 changes again. How do I fix this problem?

[@oluwaseunogunmolu]

Yes. The number will change because it is generated from time. The solution is to add generic number or text to the Unique Number. for Example GHA-XXXXX-UNIQUE-NUMBER

Thank you,however the formula recounts,when one makes changes to the form.
Instead i will suggest use once(uuid) or you can extract 10 characters, or only 10digits or more from it.
Thank you once more.

[@valentineonuchukwu9694]

Or add this in the calculate question ,
regex(substr(once(uuid), 0, 10), '^[0-9]{10}$')
The use the data column name to display the result in note question.
This method make sense beacuse some devices time might change

[@oluwaseunogunmolu]

There are many methods depending on your choice. This is just for a starter to have a glimpse of it. I can do more than 5 methods but it won’t make sense doing them in one video.

Really helpful Thank you
How if I want to code the country, hospital and participant ID like (01-02-9999) 01-country code , 02-hospital(university)code and from 0001 to 1000- participant ID

[@NMCCOOP]

i got it thank to you but in mobile while filling the form all the digits are not shown. And also while saving data all numbers are not recorded. Ihave tried of 9 digits

Create Kobo tool with identity name in the beginning.
