A complete international number is built from four parts. Here's the anatomy and the dialling order.
Number anatomy
Format follows ITU-T Recommendation E.164 the international public telecommunication numbering plan.
Press + on a mobile (hold the 0 key), or dial 00 from most countries / 011 from North America.
Dial +98. This identifies Iran on the global telephone network.
Type the first part of the local number. Drop the leading 0 if there is one.
The remaining digits route the call to the specific line in Tehran or elsewhere.
To call Iran on WhatsApp, save the number with +98 and no exit prefix — WhatsApp dials from your contacts, not a dial pad. Voice and video calls are free over data.

TKOS provisions +98 DIDs and termination through direct carrier interconnects.
Whether you're reaching Iran for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.
Tehran (Iran) routes benefit from active noise cancellation — local background noise at the Tehran end is less disruptive when your mic is already clean.
Tehran is ~6,950 km away — expect ~280ms round-trip. A wired ethernet connection keeps packet loss below 0.1%.
Schedule Iran calls during Tehran business hours — 09:00–17:00 Asia/Tehran — your contact will be at their desk in a quiet space rather than taking the call on the move.
