Electrical Grid, Voltage & Plug Compatibility
- Nominal Grid Parameters: Operates on a single-phase standard of 230 V, 50 Hz.
- Plug & Socket Hardware: Type C, F. In practical terms this covers Type C (ungrounded 2-round-pin Europlug, 2.5 A) and Type F (grounded German Schuko 2-round-pin, CEE 7/4, 16 A).
- International Traveler Guidance: Devices operating on 100–240 V (smartphones, laptops) require only a mechanical pin adapter. Single-voltage appliances from differing voltage regions require a certified step-down/step-up power transformer.
Telecommunications, Dialing & Emergency Dispatch
- International Dialing: The country calling code is +98. Outbound international calls from within the country require dial prefix 00 followed by the destination country code.
- Emergency Dispatch: Consolidated emergency services are reached at 110 (Police) / 115 (Medical) / 125 (Fire). Calls are automatically routed to local public safety answering points with emergency vehicle dispatch.
Transportation, Driving Standards & Road Regulations
- Traffic Flow: Road traffic drives on the right (RHT) with Left-Hand Drive (LHD) vehicles.
- Standard Speed Limits: General regulatory speed limits default to 50 km/h (31 mph) in built-up urban and residential zones, 80–100 km/h (50–62 mph) on undivided rural roads, and 110–130 km/h (68–81 mph) on grade-separated divided motorways/expressways (unless lower local limits are posted).
- Safety Requirements: Mandatory seatbelt compliance for all occupants, zero-distraction handheld mobile phone bans while driving, and mandatory in-vehicle warning triangles.
Commerce, Currency & Document Standards
- Official Currency: Legal tender is the Iranian Rial (IRR, ﷼).
- Document & Paper Standards: Standard office printing, official government gazettes, and legal filings strictly utilize ISO 216 A4 (210 × 297 mm). Standard business correspondence pairs with standard business envelopes.
- National Time Zone: UTC+3:30 (IRST, permanent year-round since Sept 2022).
Postal Addressing & Administrative Divisions
- Postal Architecture: Postal delivery utilizes 10 Digits (Postal Code on Utility Bills).
- Standard Address Format: Structured in standardized hierarchy: Recipient Name → Street Address / Building Unit → Postal Code + City/Town → Province/State → Iran.
