Sticker Price vs Real Price: Why Delivery Rate Changes Everything
2026-08-26 · SMS-GO Research Team · 5 min read
Written by the team that operates SMS-GO. Figures reflect first-hand operation and an August 2026 audit of 16 providers\u2019 published price data. Pricing moves, so treat specific numbers as a snapshot.
The price you see is not the price you pay. If a number fails to deliver half the time, you are effectively paying double per successful verification. This is the single most misunderstood part of SMS-verification pricing, and it is why the cheapest quote is often the most expensive option.
The effective-price formula
Effective price = sticker price divided by delivery success rate. A $0.20 number that delivers 80% of the time costs $0.25 per successful code. A $0.10 number that delivers 50% of the time also costs $0.20 per success — and wastes more of your time.
Delivery success on verification pools is commonly reported in the 55-90% range. That range is enormous: it means the same sticker price can be a bargain or a ripoff depending on the pool.
Why pools fail
A failed delivery is almost never random. It is a number that the platform has already decided not to trust.
- VoIP ranges that the platform blocklists.
- Recycled numbers that appear on other accounts.
- Country mismatch, where the number does not fit the account region.
- Carriers delaying or dropping the SMS.
The refund is what makes it fair
If a failed attempt refunds, your cost per success approaches the sticker price, because you only pay for numbers that work. If failures are not refunded, every dead number is money you paid for nothing, and your real cost climbs with every retry.
This is why an auto-refund policy is not a nice-to-have. It is the mechanism that aligns the sticker price with what you actually pay.
What to look for
Judge a provider on cost-per-success, not sticker.
- Ask for the delivery rate on the specific service, not a global average.
- Prefer physical pools for strict platforms, where failure is most common.
- Require an auto-refund window, so failures do not cost you.
- Track your own success rate per service after you start.
Questions, answered
What is a normal delivery success rate?+
Commonly reported between 55% and 90%, depending on pool quality and how strict the platform is. Physical pools on strict platforms sit at the better end.
How do I calculate the real price?+
Divide the sticker price by the delivery rate. A $0.20 number at 80% delivery costs $0.25 per successful code.
Why should I care about refunds?+
If failures refund, you only pay for working numbers, so your cost per success stays near the sticker. Without refunds, every failure raises your real cost.
Can I know the success rate before buying?+
Ask the provider for the per-service rate, then verify with your own first orders. Global averages hide the service you actually use.
