Romania's country code is +40. From the UK, dial +40 then the Romanian number with the domestic leading 0 dropped. A Bucharest landline printed as 021 XXX XXXX is +40 21 XXX XXXX. A Romanian mobile printed as 07XX XXX XXX is +40 7XX XXX XXX. Do not keep the 0 after +40: +40 021 is a misdial.
How to dial
Use one of these origin formats:
- ›+40 plus the national significant number (usual on a mobile)
- ›00 40 plus the same digits from a UK landline that still needs the international access prefix
Ofcom's National Telephone Numbering Plan designates 00 as access to international telephone numbers from the UK. + is a substitute on many mobiles. Do not assume every device accepts the same input.
More numbers: call Romania. Area codes: Romania calling codes.
The ITU E.164 list assigns 40 to Romania. Bucharest geographic numbers use 21 (printed 021). Other counties use 3-digit area codes after the 0, for example Cluj-Napoca 264 (printed 0264). Romanian mobiles use 7 after +40 (printed 07xx). A prefix is a format hint, not proof of the current network.
Cost
A call from the UK to Romania is an international call from home. That is not the same as roaming while you are in Romania.
EE's call-abroad page sells International Pass and International Extra add-ons for calls from the UK. Inclusive minutes, if any, are plan-specific. Check whether Romania is named on the destination list.
Listed WorldDial rates checked on 13 September 2026: $0.03/min to landlines and $0.05/min to mobiles, in USD. Calls are billed in whole minutes, rounded up. Check the current rate for your number on rates before adding credit.
If Romania is already in your UK calling allowance, use your handset. If it is not, you can place the call in the browser. How calling works: how it works.
When 0800 is the wrong number
Romanian 0800 is a domestic freephone range. Do not assume a domestic toll-free number will work from the UK. 0801 is a different range and is easy to confuse with 0800. Use the number the organisation publishes for international callers.
ANAF contacts for overseas callers are on ANAF from abroad.
Time difference
Romania is two hours ahead of the UK throughout the year. Both countries change their clocks on the same schedule. Check the organisation's local opening hours before calling.
Format mistakes to avoid
- ›Keeping 021 after +40 (Bucharest must be +40 21)
- ›Assuming an 0800 or 0801 number will work from the UK
- ›Confusing roaming in Romania with an international call placed from the UK
