How to Dial Iran from the UK

1. UK Exit Code

Dial 00. This is what lets your call leave the United Kingdom.

2. Iran Code

Dial 98. That is the country code that routes you to Iran.

3. Drop the Zero

Strip the leading '0' from the area or mobile code.
For example, 021 turns into 21.

Heads Up: Sanctions and Blocking

UK mobile carriers such as EE, O2, and Vodafone often block calls to Iran because of international sanctions or routing problems. Intercalling relies on specialized VoIP routes so your call still reaches Hamrah-e-Aval, Irancell, and landlines at low rates.

Calling Iran from United Kingdom: what to know

Iran answers on the country code +98, with the capital in Tehran and most business concentrated around Tehran, Mashhad and Isfahan. The working language for business is Persian (Farsi), and local offices generally keep hours of 8:00 to 16:30 Saturday Wednesday; Thursday morning only; Friday is the weekend.

From United Kingdom the outbound access code is 00, so a manual dial reads 00 then +98 then the local number. Intercalling removes that step: the call goes through your browser, so there is nothing to install and no SIM card to swap when you travel between United Kingdom and Iran.

Most mobiles in Iran sit on operators such as MCI (Hamrah-e Avval), Irancell, RighTel. Iran runs Saturday Wednesday work week (Thursday half-day, Friday off).

Iran runs on UTC plus 3:30, and it does not observe daylight saving, so the time difference stays constant through the year.
