+90 5XX numbers: Turkish mobile lines

A +90 number whose next digit is 5 (for example +90 532, +90 542 or +90 555) is a Turkish mobile line. Turkey's regulator BTK assigns the 5XX codes to mobile operators and virtual operators, and since mobile number portability started in 2008 a number can move between networks while keeping its prefix.

Who uses +90 5XX numbers?

The Information and Communication Technologies Authority (BTK) manages Turkey's national numbering plan. In the plan notified to the ITU in March 2018, BTK lists 501, 505-507, 530-549, 551-555 and 559 as mobile numbers, 510, 516 and 524 as MVNO numbers, and 592 as satellite (GMPCS) mobile numbers. All numbers are 10 digits. Mobile number portability has been mandatory since 2008, using a central reference database run by BTK.

Prefix	Operator	Note
0532, 0533, 0535-0539	Turkcell	Listed by Turkcell as its GSM prefixes
0542	Vodafone Turkey	Vodafone's own customer line is in 0542
0555	Türk Telekom	Türk Telekom makes mobile campaign calls from a 0555 number

Who is calling you from a +90 5XX number?

Most +90 5XX calls and WhatsApp messages come from private individuals and small businesses. Since April 2026, BTK rules let mobile operators and their dealers make marketing calls only to their own subscribers, so a 5XX caller offering you another operator's tariff is breaking the rules. Calls claiming to be police, prosecutors or soldiers are a long-running fraud pattern in Turkey.

Scams seen with +90 5XX numbers

Fake police, soldier or prosecutor calls: Turkey's General Directorate of Security (EGM) warns about callers who claim your name is linked to a terrorism or organised-crime investigation and demand money or gold. EGM says public officials never ask for money by phone and tells people to call 155.
Callers asking for card PINs or bank details: Jandarma warns that no public official or bank employee asks for card passwords or bank details on the phone.

What to do about a call from +90 5XX

Frequently asked questions

Which operator is 0532?

0532 is a Turkcell prefix. Because of number portability, the line may now be with another operator.

Is +90 5 always a mobile number?

Yes. BTK's plan reserves the 5XX codes for mobile, MVNO and satellite mobile numbers. Landlines use 2XX-4XX area codes.

Can I tell the current operator from the prefix?

No. Mobile numbers in Turkey have been portable since 2008, so the prefix reflects the original allocation only.

Someone called saying they are the police and need money. What do I do?

Hang up. EGM says officials never ask for money by phone. Call 155 to report it.
