Every day, thousands of valuable domains expire and become available for open registration. RRPproxy’s high-performance backordering service can improve your chances of obtaining these expiring domains quickly, easily, and with more success.

RRPproxy Backorder service covers hundreds of different TLDs, making it a leader in terms of TLD selection anywhere industry-wide.

How do Backorders work?

Resellers have access to lists of domains that are about to be released in the following hours, but Backorders for any domain can be submitted at any time. Resellers can place Backorders for currently registered domains in supported TLDs via the web-interface or through the API.

These Backorders remain dormant in the system until the requested domain is scheduled to be deleted by the Registry. Backorders in this condition have the status UNPAID in the system (if the Backorder has been prepaid, the status will show as PAID).

Once a release date for the domain has been determined, a Finalization Date is calculated by the system. This is the deadline until which new orders for the domain are accepted by the system. This is also the deadline to cancel existing Backorders. Reseller can check the Finalization Date of a specific domain by checking the pending delete lists or through the Backorder search function. This information is also provided by the system when querying existing Backorders.

6 hours before the Finalization Date, the Backorder system will lock the funds necessary to cover the cost of the Backorder in the Reseller's account, according to the listed price for the specific Reseller's tier. Once funds have been secured, the status of the order turns to "PAID".

If the Reseller account does not hold enough funds to cover the cost of the Backorder, the system will keep retrying until the Finalization date.

Only orders for which we were able to secure funds before the finalization date will be considered valid. Once the finalization date has passed, these orders will have the status "PROCESSING" in the system. The system will only attempt to register domains for which at least one valid order exists. Also, in case our system catches a domain for which multiple valid orders have been received, only those customers with valid orders will be invited to the auction.

In case the system fails to register the domain, the lock on the funds in the deposit is released and no charges are applied to the Reseller account.

In case of success, the next step will depend on the number of valid orders received for that domain. In case of a single valid order, the system will finalize the charge of the amount that was locked for the Backorder in the Reseller's account. In case of multiple valid orders, a private auction will take place among the customers that had submitted those orders.

Current Limitations

RRPproxy offers Backorders in cooperation with its sister company HEXONET. All orders are collected in a common pool and processed by HEXONET.

The following functionalities currently offered by HEXONET are not yet available via RRPproxy, but we are working to add them as soon as possible:

- Backorder of Premium names in the TLDs that support them (RRPproxy will return an error if a Backorder is submitted for a premium name)

- Custom email alerts

- Backorders in TLDs for which the use of an extension is required:

  • abogado
  • attorney
  • bayern
  • ca
  • ch
  • country
  • dentist
  • fr
  • it
  • law
  • lawyer
  • li
  • ltda
  • nl
  • nu
  • nyc
  • org.co
  • se
  • srl
  • uk (and 2ld.uk)
  • us


In case the Backorder system is successful in registering a domain for which multiple valid orders have been received, an auction will take place on a dedicated auction portal at Premiumsale.com.

The customers who submitted the backorders will receive an email directly from the auction platform inviting them to register an account to participate in the auction. Auctions are private, so only the customers who have placed a valid Backorder are invited to participate.

Invitations are sent to the email address listed in the OWNERCONTACT that was used in the Backorder. Resellers should advise customers to whitelist the domain premiumsale.com in their spam filters to avoid missing any important communication.

  • Auction Start time: 20:00 UTC
  • Starting Bid: 10.00 USD
  • Bidding: 5.00 USD increments
  • Currency: Only USD at this time
  • Auction Duration: 3 Days - If a bid is placed in the last 2 minutes auctions are then extended by 2 more minutes
  • Proxy Bids: Supported

After the auction is finished

Upon completion of an auction, the winner has 7 days to pay the auction price. The following payment options are available:

  • Paypal
  • Wire Transfer

The auction price does not include the Backorder fee, which is charged to the account of the Reseller that submitted the winning Backorder once the Auction Provider has confirmed that the winner has paid the auction price.

In case an auction ends without any bids from any of the registered participants, the domain is assigned to the customer whose Backorder was received first, based on the creation date associated with the Backorder in the Backorder system.

Important Things To Remember

RRPproxy offers Backorders in cooperation with its sister company HEXONET. All orders are collected in a common pool and processed by HEXONET.

To maximize the chances of success, the Backorder system uses multiple accreditations from various Registrar Partners.If the registration is successful, domains backordered via RRPproxy are available to be managed by the RRPproxy interfaces just like any other domain registered via RRPproxy. For most extensions, the RRPproxy system will automatically transfer the domain to RRPproxy at the time of the subsequent renewal.

While a backorder system increases the chances of obtaining a dropping domain name, there is no guarantee of success, as many other companies also have Backorder systems that compete with ours. This is particularly true for generic domains that are considered valuable on the aftermarket.

Backorders are only processed if the system was able to secure a deposit from the Reseller account by the Finalization Date of the domain object of the Backorder. Resellers should make sure there are enough funds in their accounts to cover the cost of the Backorders and any other operation they need to run in the same period. RRPproxy also offers the possibility for Resellers to prepay a Backorder in advance, in order to avoid issues with sudden dips of available funds in the Reseller’s deposit due to Backorders processing kicking in.
