Pick the country, then enter the number without the country code.

The +966 and the 0 do the same job, so a number is never written with both.
A Saudi phone number checker reads a number's format first and then checks it against Saudi Arabia's numbering plan.
This is the path one check takes. A number can be written correctly and still not be assigned to anyone, so the format check alone is not the answer.

- You see valid or invalidWith the line type and country in a few seconds, and the carrier or network where one is listed.
A Saudi mobile number has 9 digits after +966 and starts with 05, so any other length is not a valid mobile.
These lengths come from the numbering data for Saudi Arabia. A mobile number has 10 digits when it is written at home with its 0.
| Number type | Starts with at home | Digits after +966 | Written at home |
|---|---|---|---|
| Mobile | 05 | 9 | 051 234 5678 |
| Landline | 01 | 9 | 011 XXX XXXX |
Three common mistakes make a Saudi number fail the check, and each one is quick to fix.
Keeping the 0 after +966 adds a digit.
The 0 is only for dialing inside Saudi Arabia, so +966 051 234 5678 is wrong. Drop the 0 and write +966 51 234 5678.
Typing too few or too many digits makes a number invalid.
A mobile number has 9 digits after +966. With 8 or 10 it cannot be a valid mobile, so look for a missing or doubled digit.
Leaving the wrong country selected changes how the number is read.
The checker reads a number by the rules of the country selected above, so keep Saudi Arabia selected for a +966 number. Paste a number with its + and country code and the country is read from the number itself.
These are the questions people ask most about checking Saudi phone numbers.
How do I check if a Saudi phone number is valid?
Enter the number in the box above with Saudi Arabia selected. The free checker returns valid or invalid in seconds, with the line type and country. Type it the way it is written at home, such as 051 234 5678, or in full as +966 51 234 5678.
How many digits is a Saudi phone number?
A mobile number has 9 digits after +966, or 10 written at home. A landline has 9 digits after +966, such as +966 11 XXX XXXX.
What does a Saudi mobile number start with?
Mobile numbers start with 05 at home, which is 5 after +966. The next digit is 0, 1, 3, 4, 5, 6, 7, 8 or 9.
How do I write a Saudi number for an app or an SMS tool?
Use the E.164 form: a plus sign, 966, then the number without its leading 0 and no spaces, such as +966512345678.
Does the Saudi phone number checker show the carrier?
It shows the carrier or network where one is listed. Numbers outside the US and Canada are checked against the numbering plan of their country rather than live carrier data, so some come back with no carrier name.
Does valid mean the Saudi number is active?
No. Valid means the number is real, correctly written for Saudi Arabia and assigned. Whether a line is switched on and reachable right now is a different question, and the free HLR lookup answers it.
Can I check a whole list of Saudi phone numbers?
Yes. This free tool checks one number at a time. A 7-day free trial opens CSV upload and the API, at 1 credit a number.
Does the person know I checked their number?
No. The check reads records only. No call or text goes to the number, so its owner is never told.
What are the landline area codes of Riyadh, Jeddah and Dammam?
At home the codes are 011 for Riyadh, 012 for Jeddah and 013 for Dammam. From abroad the 0 is dropped, so Riyadh is +966 11. The area code is part of a landline's digits, and a mobile number has none.
