Porting Days and Supported Hours
To ensure a successful porting experience and minimize the risk of service disruption, all number porting activities are completed within supported carrier hours. Our porting schedule is intentionally aligned with both winning and losing carrier availability to ensure rapid response if issues arise during or immediately after a port.
Standard Porting Hours for US/CAN numbers
All US/ CAN number ports are scheduled within the following supported windows (Eastern Time):
-
Monday – Thursday:
8:00 AM – 5:00 PM ET
-
Friday:
8:00 AM – 2:00 PM ET
Why These Hours Are Enforced
Carrier support availability — both on the gaining (winning) and losing carrier side — is limited outside standard business hours. While availability varies by carrier, most providers have reduced or no port-level support after 5:00–6:00 PM ET, and significantly limited support late Fridays and over weekends.
Porting outside of supported hours increases risk, including:
-
Inability to reach the losing carrier to:
-
Obtain real-time concurrence on the port
-
Troubleshoot unexpected rejections or delays
-
Delayed removal of translations or routing on the losing carrier’s network, which can result in:
-
One-way calling
-
Intermittent call failures
-
Calls continuing to route to the old provider
-
Limited or unavailable carrier escalation paths if issues arise
-
Extended out of service exposure until the next business day
To mitigate these risks, all ports are scheduled only during hours when both carriers are actively supporting port activity and post port validation.
Friday Porting Limitations
For additional risk mitigation and carrier alignment:
-
Carrier partners do not support project ports past 2:00 PM ET on Fridays
-
As a result, all Friday porting concludes at 2:00 PM ET
This limited Friday window ensures there is sufficient time to:
-
Obtain full concurrence from the losing carrier
-
Confirm translations are removed and routing is properly updated
-
Validate call completion post port
-
Address any issues before weekend carrier support limitations begin
Key Notes
-
Port requests scheduled outside supported hours will be moved to the next available business day
-
These hours apply to both standard and project ports
-
Porting outside supported hours is not recommended due to the increased risk of service disruption and delayed resolution
⚠ Supported Porting Hours
Ports are completed only during carrier supported hours to ensure both the winning and losing carrier are available for concurrence, translation removal, and immediate issue resolution.
