Facebook pages live on the counter, not the feed
For a local business, the Facebook page is often the most complete thing it has online: opening hours, reviews, the menu, the message button. Yet it's almost never found by search inside Facebook — it's found by someone standing in front of the shop. A QR code on the counter, the menu or the door turns that moment into a like, a review or a message.
Encode your page's username, not the long numeric URL Facebook shows before you claim one. If your page still lives at facebook.com/profile.php?id=… go to your page settings and set a username first; the resulting link is shorter, scans from further away, and looks like you on the printed preview.
The page link also works as a review funnel. Scanning lands on the page, where the reviews tab is one tap away — which is why codes by the till and on receipts consistently collect more reviews than a line of text asking for them.
Every Facebook code made here is static: the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down. There's no account, no watermark and no scan limit — download it once and it keeps working for as long as the Facebook link behind it does.
