Booking.com and New Regulations - How to Update Your Host Profile

Booking.com and the New Regulations - How to Update Your Host Profile Step by Step

Booking.com is the largest booking platform in Poland and Europe. Over 60% of short-term rental bookings in Polish cities go through this service. Starting May 20, 2026, Booking.com must comply with EU Regulation 2024/1028, and that means specific changes for every host. In this article, we show you step by step what you need to do in the Booking.com panel to keep your listings active after the new regulations take effect.

How Booking.com Is Implementing EU Regulation 2024/1028

Booking.com is one of the platforms the regulation directly obligates. The service must require a registration number from hosts, verify its accuracy with the national register (in Poland, CWTON), remove listings without a valid number, and report reservation data to Polish authorities.

Booking.com has started preparing for the regulation's implementation ahead of time. The Partner Hub panel already features sections related to regulatory compliance, and the platform sends notifications to hosts in countries approaching the implementation deadline.

It's worth knowing that Booking.com has experience implementing similar regulations in other countries. The registration system is already operational in France, Spain, the Netherlands, Portugal, and many regions of Italy. The Polish implementation is based on the same mechanisms.

What Will Change on Booking.com From May 20, 2026

• CWTON registration number will become a mandatory field in the property profile
• Listings without a number will be hidden or removed from search results
• Automatic verification - Booking.com will check the number against the CWTON database
• Reservation data will be shared with Polish authorities as required by the regulation
• Notifications and alerts - the platform will inform hosts about missing regulatory data

Where to Add the CWTON Registration Number - Step-by-Step Guide

Step 1: Log in to Partner Hub

Go to admin.booking.com and log in with your credentials. Partner Hub is the property management panel on Booking.com - this is where you make all changes to property profiles, pricing settings, and reservations.

Step 2: Select the Property

If you manage multiple properties, select the one for which you want to add the registration number. Each property requires a separate CWTON number - the number is assigned to the property, not to the host.

Step 3: Go to Property Details

In the Partner Hub side menu, find the section for property details. On Booking.com, this section may have different names depending on the panel version. Look for options like: Property details, Property info, Property profile, or General info.

Step 4: Find the Registration Number Field

In the property details section, you should see a field labeled Registration number, License number, or CWTON number. This field may be in a subsection called Legal information or Regulatory compliance.

If the field isn't visible in your panel yet, it may mean that Booking.com hasn't activated this feature for properties in Poland. In that case, check the panel regularly - the field should appear before May 20, 2026.

Step 5: Enter the CWTON Registration Number

Enter the exact registration number you received from the CWTON system. Make sure the number is correct - Booking.com will verify it against the CWTON database. An incorrect number will result in rejection and the need for correction.

Step 6: Save Changes

After entering the number, click the Save or Update button. Booking.com may display a confirmation or information about ongoing verification. The verification process with the CWTON database may take from a few hours to a few business days.

Step 7: Check Verification Status

After saving, return to the property details section and check the registration number status. Possible statuses include: Pending verification, Verified, Rejected. If the number was rejected, check whether you entered it correctly and whether it's active in the CWTON system.

Registration Number Verification

Booking.com is implementing an automatic registration number verification system. The platform connects to national register databases (in Poland, CWTON) and checks whether the number provided is valid, active, and assigned to the property at the given address.

What the verification checks:

• Number existence - whether such a number exists in the CWTON database
• Number activity - whether the registration hasn't been withdrawn or suspended
• Address match - whether the property address in CWTON matches the address in the Booking.com profile
• Host data match - whether the owner's data in CWTON corresponds to the data in the Booking.com partner profile

If the verification detects discrepancies, Booking.com may request clarification or data correction. In extreme cases - with repeated issues or suspicion of providing a false number - the platform may suspend the listing.

Data Sharing - What Booking.com Reports to Authorities

EU Regulation 2024/1028 requires platforms to share data with relevant national authorities. Booking.com must regularly provide the following information:

• Host identification data - name, surname, address, tax ID (if applicable)
• Property data - address, CWTON registration number, property type
• Reservation statistics - number of reservations in a given period, number of overnight stays, number of guests
• Revenue - total reservation value (excluding platform commission)

This data is provided to the designated national authority at least once per quarter. On request from the authority - within 15 business days. Data may be shared with local governments in aggregated form.

What does this mean for you as a host? Above all, the tax office will have access to precise data about your Booking.com revenue. Hiding income from the tax authorities will become virtually impossible.

Tax Reporting - Booking.com and DAC7

Independently of Regulation 2024/1028, Booking.com is subject to the DAC7 directive, which requires reporting seller incomes to tax authorities in EU countries. Since 2024, Booking.com has been reporting data of Polish hosts to Polish tax authorities.

In practice, this means double reporting: once under DAC7 (tax data) and once under Regulation 2024/1028 (accommodation activity data). The most important consequence for hosts: you must file your taxes honestly, because authorities have full visibility into your platform revenue.

What Booking.com Reports Under DAC7

• Host identification data (name, surname, address, tax ID, date of birth)
• Bank account number where funds are paid out
• Total revenue in a given calendar year
• Number of transactions (reservations)
• Commissions charged by the platform

Managing Multiple Properties on Booking.com

If you rent more than one property, you need to make sure each one has the correct CWTON registration number assigned. On Booking.com, each property is a separate item in Partner Hub.

How to Manage Multiple Registration Numbers

1. Register each property in CWTON - a separate registration for each address. One host can have multiple registration numbers
2. Assign numbers to the correct profiles on Booking.com - make sure the CWTON number for the apartment on Florianska Street isn't assigned to the apartment on Grodzka Street
3. Keep a mapping table - a simple list: property address, CWTON number, Booking.com property ID. This helps avoid mistakes
4. Check verification statuses for each property separately

Partner Hub - Features for Hosts With Multiple Properties

Booking.com Partner Hub offers features that make managing multiple properties easier. The dashboard shows an overview of all properties, their statuses, ratings, and reservations. The multi-property feature lets you switch between properties without logging out. Summary reports give you a revenue and statistics overview for all properties at once.

If you manage more than 5 properties, consider using a channel manager (e.g., Beds24, Cloudbeds, SiteMinder) that synchronizes data between Booking.com and other platforms and centralizes management in one place.

Common Problems and Solutions

Problem: I Don't See a Registration Number Field in Partner Hub

Booking.com is rolling out the feature gradually. If the field isn't visible yet, wait - it should appear before May 20, 2026. You can also contact Booking.com support through Partner Hub and ask about the feature availability date.

Problem: Registration Number Was Rejected

Check that the number is entered correctly (no spaces, correct capitalization). Verify that the number is active in CWTON. Make sure the property address on Booking.com matches exactly with the address in CWTON (watch for differences in street spelling, unit numbers).

Problem: My Listing Was Hidden After May 20, 2026

If you didn't add the registration number before the deadline, your listing may have been hidden or deactivated. Add the number as soon as possible - after verification, the listing should be restored. Remember that the period without an active listing means loss of ranking position and potential revenue losses.

Problem: Booking.com Requires Documents I Don't Have

The platform may request additional documents confirming your right to manage the property (rental agreement with subletting permission, ownership deed) or confirmation of CWTON registration. Prepare these documents in advance to avoid delays.

Problem: Data in CWTON and on Booking.com Don't Match

Discrepancies in address, name, or host data between CWTON and Booking.com may block verification. Standardize the data in both systems - use exactly the same address spelling and the same personal details.

Booking.com vs. Other Platforms - Implementation Comparison

Booking.com isn't the only platform that must implement the regulation. It's worth comparing the approaches of different services.

Airbnb

Airbnb has experience implementing regulations in many countries. The platform already required registration numbers in Paris, Barcelona, Amsterdam, and dozens of other cities. The process of adding a number on Airbnb is similar - through the host panel in the property details section.

Vrbo

Vrbo (part of the Expedia group) implements regulations similarly to Booking.com. The registration number field appears in the legal information section of the property profile.

Noclegi.pl

The Polish platform Noclegi.pl will need to implement the same mechanisms. As a smaller platform, it may have a less automated verification process.

Prepare Now - Don't Wait Until May 20

The worst thing you can do is wait until the last day. The CWTON system may be overloaded just before the deadline, verification on Booking.com takes time, and data issues may require multiple corrections. Start now:

1. Register the property in CWTON - the sooner, the better
2. Update the Booking.com profile - add the registration number as soon as the field is available
3. Check data consistency - the address, host data, and property type should be identical in CWTON and on Booking.com
4. Prepare documentation - house rules, GDPR privacy notice, guest register, fire safety documentation
5. Monitor communications from Booking.com - the platform will send notifications and instructions
