Scanning brings up your number in the dialler, ready to call. It suits situations where someone needs to reach you immediately and cannot type a number — driving, carrying something, or standing in the rain.
Free to use, including commercially. No watermark, no sign-up.
Everything on this page is encoded directly into the pattern, so the code works forever and needs no account. The trade-off is that it cannot change and cannot be counted.
Write it as +234 704 426 4527 so it dials correctly from abroad as well as locally.
Check the number appears exactly right in the dialler, digit for digit.
SVG for signage and vehicle livery, PNG for screens.
Let a passer-by call about the property from the pavement without typing anything.
Make a number callable from a van or hoarding people only see for a moment.
Put the right number one scan away on a machine or in a stairwell.
No. The number appears in the dialler and the person taps to call. No phone will place a call from a scan without confirmation.
Yes. Without it the number only works for people whose phone is already on your country's network, which quietly loses you anyone roaming.
Not from a static code. If you need to know which sign produced the calls, point a dynamic code at a page with your number and read the scan data by location.
