Backup codes: never let a sold-out invite code waste a click
DealPage is a referral code landing page tool that switches to your next backup code when the current one runs out, and to a restock sign-up when none are left.
The most expensive moment for a code to run out
A limited invite code runs out because people are using it. That means it tends to run out while the post sharing it is still doing well. Every reader who arrives after that point was interested enough to click and now finds an error.
There is no recovering that click. The reader does not know you have another code, and they are not going to scroll through your replies to find one. If someone else's code is a search away, that is where they go.
Where backup codes come from
Some programs give you several codes from the start. Some give one code and let you request more. Invite-only apps often give each new user a few invites of their own, so creators collect spares from friends who signed up through them.
However you get them, the habit to build is the same: the moment you have a spare, it goes into the queue, not into your notes app.
Order, quota and expiry
A backup queue needs three pieces of information per code. Its order, so the right one is shown first — usually your own code, then spares. Its quota, if the program limits uses, so the switch happens when it is used up. And its expiry date, if any, so an expired code is skipped even if it has uses left.
The used count is the tricky part. Most programs do not tell anyone else when your code is used, so you keep it roughly accurate by checking the program's dashboard. A quota that is slightly out of date is still far better than none: the worst case is that the switch happens a little late.
When every code is gone
Eventually the queue empties. What the visitor sees then is the difference between a lost click and a future one. A page that simply says “sold out” loses them. A page that says “new invites are coming — leave your email and you will hear first” keeps them.
That list is worth more than it looks. The people on it have already shown they want the product. When you get the next batch of codes, they are the first people to tell.
Making the switch automatic
None of this works if it depends on you watching the post. The switch has to happen on its own, at any hour. That rules out pasting codes into posts, and it rules out a page you edit by hand.
In DealPage, each Deal holds a list of codes with priority, quota and expiry. The page always shows the first code that is active, not used up and not expired. When it hits its limit, the next one appears. When none are left, the page shows a restock sign-up, and short links that would have gone straight to the product go to that page instead, so the visitor sees the form.
The sign-ups land in your subscriber list, where you can see how it grows and export it as CSV. DealPage does not send emails for you; you write to the list when the new codes arrive.
A worked example with demo data
Say you are promoting an invite for Nexo Wallet, the demo product in DealPage's screenshots, with the demo code FUU2026. You set its quota to the number of uses the program gave you. You add two spare codes from friends below it, each with its own quota.
When FUU2026 is used up, the page shows the first spare. When that is used up, the second. When all three are gone, the page asks visitors to sign up for the next batch. Your post on X never changed, and no click landed on a code that did not work.
If you want to set this up, the page on backup referral code rotation walks through the settings, and the invite code page guide covers the restock sign-up in more detail.
Frequently asked
- What is a backup referral code?
- A spare code kept ready to replace the one you are sharing when it sells out or expires.
- How does the page know when a code is used up?
- From the quota and used count you enter, and from the expiry date. Most programs do not report uses to third parties, so you keep the count roughly current from the program's dashboard.
- What should visitors see when all codes are gone?
- A sign-up for the next batch rather than a dead code, so the interest is not lost.
