General question not an issue! are delivery receipts and error codes standard and same across the platform?

I was mapping the codes takin reference from this guide and this guide error codes, so just want to be sure if error and status codes are same throughout the provider gateways and they follow this standard status codes ?

thank you!

Yes and No. The website you linked, managed by MelroseLab, has errors I've never seen before and that are not even in this library. All the error after ESME_RUNKNOWNERR / 0x000000FF / 255 are not in the spec. They are using the 0x00000100- 0x000003FF range, reserved for SMPP Extensions, but its not official errors.

• Read and use the spec: https://smpp.org/SMPP_v3_4_Issue1_2.pdf
• SMSCs can return a different error depending their interpretation of the error.
• SMSCs have a reserve range, 0x00000400-0x000004FF, where they can return whatever errors they want, and are completely different between SMSC operators.
• Always talk and align error codes with ESME/SMSC operators.

Good luck
