Datatype for phone numbers in postgresql

Question

I am new to postgresql so can anyone tell me that is there any specific datatype to store phone numbers in postgresql while creating table in pgadmin or is it just string?

Solution

I recommend to use text and add a check constraint that tests the phone number for validity.

This is a good use case for domains. Particularly if you need such a column in several places, it is convenient to have a domain that includes the check constraint.
