Scan, and the dialler opens with your number already in it. One tap and the phone rings, no typing, no transcription errors, no lost lead because someone misread a digit off a van.
The scan opens the dialler with your number filled in, so the caller never has to read digits off a van or a window and type them.
Every mistyped digit is a lost call. A tel code skips the copying step entirely, which matters most on signs seen briefly or at night.
It works at the moment someone decides to call: a shop window after hours, vehicle livery in traffic, a service counter, an estate agent board.
Export a sharp PNG or vector SVG for signage, cards, and flyers, and set your own colours so the code fits the design.
Use full international format with a plus sign. Include the area or trunk code, and drop the spaces, brackets and dashes people add for readability, the dialler wants digits, and formatting characters cause failures on some Android builds.
A call code converts intent into a ringing phone within seconds, which is worthless if it rings out. Use the number that is staffed during the hours the code will be seen, and if that changes seasonally, use a redirecting business number rather than reprinting signage.
Shop windows after closing time, vehicle livery in traffic, estate agent boards, tradesman signage, service counters. These are all moments where someone wants to call and has no easy way to capture the number.
Always show the digits as well. Some people will not scan, some are on a desktop, and a visible number reassures everyone else that the code does what the label says. The code is a shortcut, not a replacement.

Reading a phone number off a moving van, a hoarding, or a window at night and typing it correctly is harder than it sounds, and every mistyped digit is a lost call. A tel: code removes the transcription step entirely. That is why it performs best on surfaces people see briefly and cannot easily photograph, the failure mode you are designing around is not laziness, it is a person with one hand full and eight seconds of attention.
Calls suit urgent, high-value, and hard-to-explain jobs: emergency plumbing, medical appointments, roadside services, anything where a conversation closes faster than a thread. WhatsApp suits enquiries people are happy to leave and come back to, and dominates in markets where it is the default channel. SMS suits keyword opt-ins and audiences with no messaging app at all. If your enquiries arrive out of hours, a call code alone will lose them, pair it with a WhatsApp code and let the customer choose.
A static tel: code leaves no trace anywhere in your analytics, because the phone dials directly with nothing in between. If you need to know which sign produced which calls, use a distinct tracking number per placement, or point a URL code at a landing page with a click-to-call button so the visit is recorded before the call starts. Both approaches cost something; guessing costs more.
