Always drop the leading 0
Romanian domestic numbers begin with 0 (e.g., 021, 0264, 07xx). When dialling from the UK, remove that initial 0 after entering +40 or 00 40. Keeping it will prevent the call from connecting.
Quick Answer
From the UK, dial 00 40 (or +40 on a mobile) then the Romanian number without the leading zero. The full sequence is: 00 + 40 + 9-digit number. Mobiles start with 7xx; Bucharest landlines use area code 21 or 31.

KEY RULES
A few format and numbering details that help your calls connect on the first try.
Romanian domestic numbers begin with 0 (e.g., 021, 0264, 07xx). When dialling from the UK, remove that initial 0 after entering +40 or 00 40. Keeping it will prevent the call from connecting.
Whether you're calling a Bucharest landline (2-digit area code + 7 digits) or a mobile (3-digit prefix + 6 digits), the national significant number is always 9 digits after the country code.
Bucharest uses a 2-digit area code (21 or 31). All other Romanian cities use 3-digit area codes (e.g., 264 for Cluj-Napoca). The subscriber number length adjusts so the total remains 9 digits.
Romanian mobile numbers use prefixes 72x, 73x, 74x, 75x, 76x, 77x, and 78x. Number portability means the prefix no longer reliably indicates the carrier.
Romanian toll-free (0800) and premium-rate (09xx) numbers are generally designed for domestic use. They may not connect or may incur separate charges when dialled from abroad. Check with your provider before calling these ranges.
TIMING TIPS
Romania is 2 hours ahead of the UK year-round (both countries observe daylight saving time on the same schedule). Plan your calls so they land during convenient hours in Romania.

TROUBLESHOOTING
If your call to Romania isn't going through, check these common causes before redialling.
The most common mistake. Romanian domestic numbers start with 0 (e.g., 0723…), but when dialling from the UK with +40 or 00 40, you must drop that 0. Dial +40 723… instead.
After the country code +40, there should be exactly 9 digits. If your call fails, count the digits — too many or too few will prevent the call from connecting.
Some UK carriers disable international dialling by default or on certain plans. Check with your provider that outgoing international calls are enabled.
Romanian 0800 (toll-free) and 09xx (premium) numbers are intended for domestic callers. They may not connect from abroad or may carry different charges. Try reaching the organisation on a geographic landline number instead.
If the number format is correct but calls still fail, there may be temporary network issues. Wait a few minutes and try again, or use a browser-based calling service like Sayfone to route the call over the internet.
