Iran mobile number regex

This pattern is designed to validate Iranian mobile phone numbers written in either domestic or international format. It recognizes optional prefixes like 0, +98, 0098, or 98, followed by a 10-digit number starting with 9 — which is the standard format for all mobile numbers in Iran.

In short, it accepts numbers such as: 09138004619, 9138004619, +989138004619, 00989138004619, 989138004619, while rejecting any number with missing or extra digits or an invalid prefix.
