Tehran's War on Duplicate Billboards: How the Capital Stacks Up Against Istanbul and Seoul

Tehran's municipal advertising authority began enforcing a long-delayed ban on duplicate image placement across city-owned billboard networks this spring, targeting commercial panels that show identical artwork within a 500-metre radius on the same street corridor. The directive, issued by the Tehran Beautification Organisation, applies to the roughly 4,200 licensed large-format panels the city manages across all 22 municipal districts.

The timing matters. Tehran is deep in a period of civic soul-searching — the kind that follows any large public gathering that forces residents to look hard at their shared urban spaces. The funeral crowds that filled Azadi Square and Enghelab Street this week gave planners an uncomfortable, real-time reminder of just how visually chaotic those corridors look when cameras pan across them. Repeated cola ads and mobile-network graphics plastered on back-to-back gantries above Chamran Expressway have drawn particular criticism from urban design researchers at the Iran University of Science and Technology, whose Urban Planning faculty published a working paper in March 2026 identifying duplicate image saturation as a measurable contributor to what they called "visual noise fatigue" in commuter corridors.

What Tehran Is Actually Doing

The Beautification Organisation's enforcement unit has issued removal notices to 317 advertising contractors since April 1, according to figures the organisation posted to its public bulletin board on Shahid Beheshti Avenue. Contractors have 14 days to replace duplicate creatives or face fines starting at 85 million rials per panel per day. Districts 6 and 7 — covering the dense commercial corridors around Vali-e-Asr Avenue and Mirdamad Boulevard — account for more than 40 percent of the notices issued so far.

The city is also piloting a digital inventory database that would let advertising buyers see, in real time, which image assets are already running within proximity thresholds of any proposed placement. The pilot launched in District 3 in May 2026 and is expected to expand to Districts 1 and 2 — Tehran's wealthiest and most billboard-dense zones — before the end of the Iranian calendar year. The system was built in partnership with the Tehran ICT Organisation, which manages the city's smart-city infrastructure from its offices near Mellat Park in northern Tehran.

How Tehran Compares Globally

Istanbul moved faster. The Istanbul Metropolitan Municipality rolled out a near-identical proximity rule for its IBB-controlled panels in 2023, covering roughly 6,800 sites across the European and Asian sides of the city. By the end of 2024, Istanbul's compliance rate among licensed contractors was reported at above 80 percent, according to IBB's published annual billboard audit. Seoul has gone further still: the Seoul Metropolitan Government's Outdoor Advertisement Management Centre uses an AI-assisted review system that automatically flags duplicate image submissions before a campaign is even approved, a standard the system has operated under since 2022.

Tehran's current approach is enforcement-after-the-fact rather than pre-clearance. That distinction is significant. Pre-clearance systems, as operated in Seoul and increasingly in Kuala Lumpur, remove the burden from inspectors and put it on the buyer before printing costs are sunk. Tehran's contractors are still producing physical vinyls, discovering they have a duplicate-proximity problem, and then absorbing removal costs — an inefficiency that smaller agencies along Jordan Street's advertising cluster say has eaten into already tight margins this year.

The digital inventory pilot in District 3 is the clearest signal that city hall understands the gap. If it scales as planned, Tehran could reach a pre-clearance model by late 2027. The Iran Advertising Association, which represents agencies operating in Tehran, has publicly supported the database system, arguing it reduces compliance guesswork. Getting Districts 1 through 10 fully onto the platform before the next municipal budget cycle in March 2027 will be the practical test of whether the programme is real reform or an announcement that quietly stalls.

For businesses advertising in the capital right now, the practical advice is straightforward: before submitting any campaign to the Beautification Organisation for approval, check the District 3 pilot portal and request a proximity clearance report even for districts not yet on the live system — the organisation's licensing desk on Shahid Beheshti Avenue is issuing informal checks on request while the full rollout proceeds.
