Use a regular expression (https://docs.opendatakit.org/form-regex) as a constraint.

I haven't tested it, but regex(.,'^[0-9]{5}-[0-9]{7}-[0-9]{1}$') should work.

I'd recommend you use a text field with the numbers appearance. https://docs.opendatakit.org/form-question-types/#number-text-widget has more.

Dear Yaw Anokwa,

regex(.,'^[0-9]{5}-[0-9]{7}-[0-9]{1}$)')
It's accepting numbers regarding the above format and not showing any wrong message.

Please guide me.

There is a ‘)’ after the ‘$’. Remove it.
