In Thailand, "add us on LINE" is closer to a shop front than a website is. A printed code that adds you in one scan removes the step where somebody has to search for your name, find three accounts with similar names, and guess.

The confusing part is that there are several different LINE codes and they do different things.

Which code do you actually want

CodeAdds you asBest for
Personal QR (in LINE, from your profile)A personal friendOne-person businesses, freelancers
Official Account QRAn OA followerAny shop with more than one staff member
Group invite linkA group memberCommunities, classes, building residents
Open Chat linkAn anonymous memberLarger public groups

For most small shops the honest answer is the Official Account. It is free at the entry tier, it separates work from your personal chat, more than one staff member can answer it, and it survives you changing your phone.

Your personal QR is fine if you genuinely are the business. Just be aware that every customer you add is a personal friend with access to your timeline, and that a phone change is a problem.

Getting a printable code

Personal: open LINE, go to your profile, and find your QR code. There is a save or share option that gives you an image file.

Official Account: in the LINE Official Account Manager, look for the QR code or "gain friends" section. It gives you a downloadable image, usually at a decent resolution.

Both give you a picture you can put in a design. If the resolution is poor, or you want it in your own layout at a specific size, take the URL instead — your OA has a public link, typically in the form lin.ee/... — and paste that into our website QR generator. You get a clean vector SVG at any size, which is what a print shop wants.

That is the practical reason to make it yourself: LINE gives you a fixed-resolution PNG, and a print shop wants something that scales.

What to write next to it

Add us on LINE is the minimum. Better is saying what they get:

  • Order on LINE — reply within an hour
  • Add us for this week's specials
  • Questions about your order? Add us on LINE

Print the LINE ID as text underneath as well. Some people prefer to search, some phones will not scan, and some customers are looking at a photo of your sign that a friend sent them. One line of text catches all of that.

Where to put it

PlacementWhy
Counter or tillWhile they wait to pay
Packaging or bagRead at home, where the repeat order happens
ReceiptSame, and they keep it
Delivery noteThe moment they might want to ask something
Market stall frontTurns a one-off sale into a contact
Shop windowFor people who arrive after closing

The packaging one is underrated. A sticker on the bag is the code that leaves with the customer, and it gets scanned at home when they are relaxed rather than at a counter when they are being watched.

Sizing and printing

Nothing special — the usual rules apply:

  • 2 × 2 cm minimum on a receipt or a small sticker
  • 4 × 4 cm on a counter card
  • 10 cm or more in a window
  • Keep the white margin around it; see the quiet zone guide
  • Matte, not glossy, if it will sit under a light

Full sizes by placement are in the print size guide.

The thing that catches people out

If you print your personal LINE code and then change your phone number or account, every printed copy is dead. There is no way to repoint it.

An Official Account link is more stable, and if you point the QR at a short URL on your own domain that redirects to your OA, you can change where it goes without reprinting anything. That is the same principle as pointing a menu code at a page you control.

Before you print a batch

Scan your own code with a phone that is not logged into your account — ideally a colleague phone. You want to see what a stranger sees: the right account name, the right profile picture, and an add button rather than an error.

Then run the pre-print checklist before ordering stickers for every bag.

Make your LINE code — paste your link, download an SVG, print at any size.
