Scottish Landlord Registration Number Format: What It Looks Like and Where to Display It

The 16-Digit Registration Number

When your local council approves your landlord registration application in Scotland, the central portal assigns a Landlord Registration Number (LRN). The format is standardised across all 32 councils:

XXXXXX/XXX/XXXXX

That's six digits, a forward slash, three digits, a forward slash, and five digits — 16 characters including the separators. Each local authority maintains its own registration entry, and the LRN identifies the entry for that council area rather than an individual property. If you own five properties in one council area, you use that area's LRN for all five; if you let in two council areas, you need to register in both and use the number for the relevant area's entry.

For jointly owned properties, the lead owner's LRN is the one displayed in advertising. Secondary joint owners have their own linked registration entries, but the lead owner's number satisfies the advertising requirement for the property.

Where You Must Display It

Section 92B of the Antisocial Behaviour etc. (Scotland) Act 2004 makes it a statutory offence to advertise a private rented property without displaying the landlord's registration status. Every written and digital advertisement must show either:

• Your 16-digit LRN in the XXXXXX/XXX/XXXXX format, or
• The exact phrase "landlord registration pending" if you've submitted a valid application and paid the fees but the council hasn't issued a decision yet

This applies to:

• Online portal listings — Rightmove, Zoopla, OpenRent, and any other property platform
• Letting agent window displays — the agent's physical office cards and property sheets
• Social media posts — Facebook Marketplace, Gumtree, Instagram, X/Twitter
• Newspaper and magazine adverts — including local classifieds
• Your own website — if you list the property directly

There's one exemption: physical "To Let" boards displayed outside the property are excluded from the requirement, because reusable boards can't practically be updated for each landlord. Everything else — print or digital — must carry the number.

Alongside the LRN, rental advertisements in Scotland must also display the property's Energy Performance Certificate (EPC) energy efficiency band. A compliant listing shows both: the LRN (or pending statement) and the EPC rating.

What Happens If You Don't Display It

Publishing a written advertisement without the required LRN or "landlord registration pending" is an offence under Section 92B and can attract a summary fine.

The fine for advertising without the required registration status sits alongside the broader penalties for unregistered letting. If you're advertising without being registered at all (not just missing the number from the advert), you're exposed to the full £50,000 fine for letting without registration under Section 93.

Common Mistakes

Displaying the wrong number. If a property changes hands, the previous owner's LRN does not cover the new owner. Registrations are non-transferable — the new owner must hold an approved registration or have submitted a complete application with fees paid before letting. Adverts must say "landlord registration pending" while the council processes that application.

Abbreviating the number. The 16-character format with forward slashes is the standard. Some landlords drop the slashes or truncate digits when entering it into property portals that have character limits. If the portal field is too short, enter it without spaces but with the slashes — most platforms accept the full format.

Confusing LRN with LARN. Your Landlord Registration Number (LRN) is your registration as a property owner. A Letting Agent Registration Number (LARN) is your agent's registration on the separate Scottish Letting Agent Register. The advertising requirement is for the landlord's LRN, not the agent's LARN — though both may appear in a listing.

Using "registration pending" when it isn't. The phrase "landlord registration pending" has a specific legal meaning: you've submitted a complete application and paid the fee, and the council is processing it. You can't use it if you haven't actually applied. An advert claiming pending status without a submitted application is a false statement.

Finding Your Number

Your LRN is on the approval confirmation the council sends when your application is processed. It's also visible when you log in to your account at landlordregistrationscotland.gov.uk. If you've lost track of it, you can search for yourself on the public register by entering your name or one of your registered property addresses — the search results display the LRN.

Tenants and letting agents can use the same public search to verify any landlord's registration status. If a search for your property returns no result, it doesn't necessarily mean you're unregistered — the search only shows approved entries, not pending applications. But it does mean anyone checking will see no record, which can create friction with prospective tenants.

The Scotland Landlord Registration Guide includes advertising compliance templates with the correct format for different platforms, plus the pre-application audit checklist that covers everything from safety declarations to the number display requirements.
