LRN - Location Routing Number

LRN stands for Location Routing Number service, and is the process by which calls are sent and routed via an operator.

Why use our LRN service?

With our LRN service, your Least Cost Routing Engine is ensured your calls are sent using the cheapest route at that moment, regardless of the time of day.

Not only can it save you money, but with accurate routing, you can also minimise the amount of calls that are dropped.

LRN with Bulk Solutions

At Bulk Solutions, we use real time data to ensure that we are always able to find the best value route for your calls at any moment.

We also allow extended lookup for you to see all available information on each call and number.

Learn about LRN

The same person making a call to the same number at different times of the day doesn't necessarily mean the call should be routed the same way!

Highly Accurate and Best Value LRN

The best route for a call changes depending on the time, even when it's the same caller phoning the same number.

With LRN lookup, we are able to find the least cost route regardless of the time of day, and route the call via the best value carrier in that moment.

We can offer this because we take our information from the Number Portability Administration Center (NPAC), meaning when a number is queried with LRN lookup, we use real-time data from that very moment to find the best route.

And with more accurate routing using this real-time data, you can avoid calls dropping too, giving you a more reliable service.
