Iran numbering plan & how to dial
Under country code +98, Iran numbers follow an open plan built from a 3-digit area or mobile prefix and a 8-digit subscriber line — 11 digits in all. A domestic "0" typically precedes the prefix, but that digit is dropped when dialing Iran internationally.
3 major networks cover Iran (Hamrah-e-Avval (MCI), Irancell (MTN Irancell), Rightel), against 78% internet penetration. VoIP is restricted and Ministry of Information and Communications Technology (ICT), Iran licenses only approved operators. Because Persian is the primary language and IRR the local currency, both should inform IVR scripts, SMS content, and support hours.
Several Middle Eastern regulators license VoIP to specific operators, so compliant, licensed termination is essential for reliable delivery into the region.
Skipping the exit code
From the US you must dial 011 before the +98 country code to reach Iran.
Keeping the national trunk "0"
That leading 0 on a Iran number is for domestic calls only; leave it out when dialing in after +98.
Ignoring the time difference
Before dialing Iran, check the local clock — it runs on Asia/Tehran, and off-hours calls tend to go unanswered.
Using non-compliant routes
VoIP into Iran is restricted by Ministry of Information and Communications Technology (ICT), Iran; grey routes are blocked or dropped, so licensed termination is required for reliable delivery.

FAQ
Calling Iran — frequently asked questions
The major networks in Iran are Hamrah-e-Avval (MCI), Irancell (MTN Irancell), Rightel. Twiching interconnects with Tier-1 carriers for direct delivery to these networks, rather than routing through cheaper wholesale transit that can degrade call quality.
Yes — calls to Iran are billed per second, not rounded up to the minute, starting at $0.09/min. Per-second billing means a 45-second call costs less than a full minute, unlike carriers that round every call up.
VoIP in Iran is restricted — Ministry of Information and Communications Technology (ICT), Iran licenses only approved operators. Twiching terminates calls over compliant, licensed routes rather than the grey-market paths that get blocked or dropped under this kind of regulation.
Yes — Iran numbers often carry a domestic leading 0 that should be dropped once you've dialed the +98 country code from abroad. Keeping that 0 in is one of the most common reasons an international call to Iran fails to connect.
Iran has 78% internet penetration, which is a useful signal for how reliably VoIP and SMS-based channels will perform there. Higher penetration generally means more consistent call quality and app-based delivery for messaging.
Hamrah-e-Avval (MCI) is among the largest networks in Iran, and Twiching interconnects directly with it for Tier-1 delivery. Direct interconnects like this are what keep call quality and answer rates consistent instead of relying on lower-tier transit.
