Serbia Phone Number validator
How the phone number format works
- Format
- Serbia phone number in national or international (+381) format
- Example
- +381601234567
Things to watch for
- Accepts national or international (E.164, e.g. +381...) format
- Validated with Google's libphonenumber; confirms the number is possible/valid for this country, not that it is currently assigned or reachable
^[+]?[0-9 ()\-]{6,}$A Serbian mobile number pairs a national trunk 0 with a two-digit operator code in the 60-69 range, written together as a familiar 060, 064-style prefix, followed by 6 or 7 more digits, e.g. 064 123 4567. Landline numbers use a separate area-code system with lengths that vary by region (Belgrade’s area code is 011). Both share the same trunk-prefix rule: the leading 0 is dropped the moment +381 is added, so 064 123 4567 becomes +381641234567.
How this validator works
Enter the number in national form (0641234567) or full international form (+381641234567); this tool checks the digit count and prefix range against Serbia’s real numbering plan using Google’s libphonenumber, entirely in your browser. Serbian mobile numbers vary slightly in total length depending on the operator code, so the validator checks the specific range tied to each 6x code rather than one fixed count.
What a pass doesn’t tell you
A pass confirms the number matches a real Serbian mobile or landline shape — it doesn’t confirm the SIM is active or the landline connected. Format validity and current network status are separate questions this tool can’t answer.
Scope: use this to catch a wrong operator code, a missing digit, or a leftover 0 after +381 before the number reaches a form — not as proof the number is reachable.

phone number FAQ
What prefixes do Serbian mobile numbers start with?
A national trunk 0 followed by a two-digit operator code in the 60-69 range, written together as 060, 064, and so on, then 6 or 7 more digits, for example 064 123 4567.
What happens to the leading 0 in a Serbian number for +381?
It's dropped, the same as most European trunk prefixes — 064 123 4567 in national form becomes +381641234567 internationally, with the 0 removed and no other digits changed.
Why do some Serbian mobile numbers have one more digit than others?
Different operator codes were allocated different subscriber-number lengths over time, so a 064 number and a 060 number can have slightly different total digit counts while both still being valid.
