Different Types of Phone Number Lookup APIs for Businesses

Phone number lookup APIs are must-have tools for businesses that want to build high-quality contact lists to support their efforts and various campaigns. These tools not only provide basic information such as the user's name and similar details. They also provide detailed information about the number such as the user's geographic location, carrier information, and even publicly available fraud information tied to the number.

Read on to learn more about the different types of phone number lookup APIs and how each can be useful to your business.

What's a Phone Lookup API?

A phone number lookup application programming interface (API) is a collection of rules and protocols that connect business systems such as CRMs to phone verification and validation services. You can implement such a tool in your business to automate caller identification, phone number data enrichment, and other tasks that improve your contact list.

You, however, should get a premium phone number lookup API from a renowned provider to ensure you're getting high-quality information consistently.

Types of Phone Lookup APIs

You can choose between the following types of phone number lookup APIs depending on your needs:

1. Phone Validation APIs

This is the type of API you would need in your business to determine whether a phone number is valid without fetching detailed information about the number. This API simply verifies whether the format a number uses is correct and whether it's tied to a carrier. A phone number that fails to use the right format or isn't attached to a carrier will typically not be valid.

You can use a phone validation API for various purposes such as verifying the information that customers provide or validating phone numbers before using them for marketing campaigns. This tool simply ensures you are sending your texts or calling a reachable number.

2. Reverse Phone Lookup API

A reverse phone lookup API is like a normal phone lookup service with additional functionality. This tool not only uncovers a caller's identity but also looks up the phone number in a variety of public databases to provide as much information about the number as possible. So whether you simply want to identify a caller or learn more about them, this would be the tool you would use.

A reverse phone lookup API is a great tool, especially for businesses that are trying to enhance customer engagement, since efforts in that direction rely on knowing as much as you can about your customers.

3. Phone Reputation

This can be a standalone API, built specifically for this purpose, or integrated into a similar tool such as a reverse phone lookup API. This one also uses public sources of information to determine if a phone number is associated with spam or unwanted calls. Every business should have this API to prevent fraud attempts, thus protecting their users and businesses from unwarranted attacks.

4. Carrier Information

Wondering how your customers' carrier information can improve your business operations? This one's quite easy. Determining the carrier information of a phone number means you also learn more about the estimated region in which a user is located.

With such information at your disposal, you can tailor your applications and services to the specific carrier or region to improve engagement with your customers. A carrier information lookup API can, therefore, enhance the overall experience for your customers by satisfying their needs and preferences.

5. Disconnected Phones

In business, you want to reduce unnecessary costs as much as you can. With businesses losing thousands of dollars every year from contacting unreachable phone numbers, you should avoid having disconnected phone numbers in your contact list as much as possible. That's where a disconnected phone lookup API comes in.

Remember that dialling disconnected numbers regularly not only results in unnecessary costs but also increases the likelihood of your business being marked as spam.
