# Things to know about Thailand number porting
<a name="porting-numbers-th"></a>

Porting in Thailand differs from other countries. Instead of the number being able to directly moved to Connect Customer, it’s necessary to route the calls from your current provider to Connect Customer. To help plan for the process here are some helpful hints.
+ Numbers being ported in to Connect Customer must be from E1 or SIP services only.
+ The E1 or SIP service, along with all associated numbers, must be routed to Connect Customer's provider's network first. Connect Customer will help coordinate this. Based on your configuration this may involve additional charges to your current provider or Connect Customer's provider to support the re-routing.
+ Once the E1 or SIP service has ported to Connect Customer's provider selected numbers from the service can be activated for use on Connect Customer. Once activated the numbers will use Connect Customer for both inbound and outbound calling.
