I received a code, but the target service says it is invalid

Open the original SMS and confirm that you entered the complete code from the newest message. Check for missing characters, spaces, or similar-looking characters.

• One-time OTP activation: the same order cannot receive another code. Do not repeatedly request new codes, because earlier codes may become invalid; purchase a new order if another code is required.
• Long-term rental / SMS URL: another code can be requested while the rental or link remains valid. Use only the newest message.

If the code from the original SMS is still rejected, it may have expired, been replaced by a newer code, or been restricted by the target service. Send support the order ID, SMS time, and a screenshot of the error.
