How the phone number format works
- Format
- Costa Rica phone number in national or international (+506) format
- Example
- +50683123456
Things to watch for
- Accepts national or international (E.164, e.g. +506...) 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 Costa Rican phone number is a flat 8 digits with no regional area code — e.g. 83123456, or +50683123456 in full international form. The country moved from 7-digit to 8-digit numbers in 2008 to keep pace with mobile growth: existing landlines gained a leading 2, and new mobile ranges were opened up starting with 6, 7, and 8, all within one unified national plan rather than city-by-city area codes.
How this validator works
Enter the number in local form (83123456) or full international form (+50683123456); this tool checks the 8-digit length and confirms the leading digit falls within a range genuinely assigned in Costa Rica’s numbering plan, using Google’s libphonenumber entirely client-side. Because the 2008 digit-length change is still recent enough that old 7-digit numbers circulate on outdated stationery, a too-short number is one of the more common reasons a Costa Rican entry fails here.
What a pass doesn’t tell you
A pass confirms the digit count and leading prefix are genuinely Costa Rican — it does not confirm the SIM is active, the landline connected, or the number still reachable at all.
Scope: catches a wrong digit count or invalid leading digit before a Costa Rican number reaches a form or CRM — not a live carrier or connectivity lookup.

phone number FAQ
Why are Costa Rican phone numbers 8 digits when neighboring countries use different lengths?
Costa Rica expanded its numbering plan from 7 to 8 digits in 2008 as mobile demand grew, prefixing existing landlines with a leading 2 and assigning new mobile ranges starting with 6, 7, or 8. Older 7-digit numbers you might see on an outdated business card no longer work without that extra leading digit.
How do I know if a Costa Rican number is a mobile or a landline?
By the leading digit. Numbers starting with 6, 7, or 8 are mobile, while 2 and 4 mark landlines — Costa Rica doesn't split numbers by city or province, so there's no separate regional area code to interpret.
Does a valid format check mean the Costa Rican number is currently in service?
No. It confirms the 8 digits and leading prefix match Costa Rica's real numbering plan — not that the SIM is active or the line connected. Only Costa Rica's telecom regulator or the carrier itself can confirm current status.
