5 Reasons to Use the Lookup API

The Lookup API uses phone number intelligence to gain in-depth insights into phone numbers, improving your communication strategies and enhancing overall business operations. The API provides data packages so you can get the right information for your business use case.

Here are five compelling reasons to integrate the Twilio Lookup API and the data packages that will help you achieve your goals.

Reason #1: Validate phone numbers

Having accurate information is crucial to reach a customer. Validating phone numbers helps you avoid wasting time and resources on incorrect data. Using the Lookup API for validation improves accuracy to help you confidently contact your customers.

Lookup can ensure correct formatting according to international dialing standards and let you know why a number is invalid. It can also identify the line type including mobile, landline, toll-free, VoIP, and more. Businesses can use this data to filter out invalid numbers before even attempting to send communications.

Phone number validation can happen at sign up or as part of a database cleanup.

Data packages to validate phone numbers:

• Formatting and Validation (free!)
• Line Type Intelligence

Reason #2: Make sure you are contacting the right person

On top of validating phone numbers, businesses need to know that the person behind the phone number is the right person they are trying to contact. Sending communications to the wrong person can waste resources, erode trust, and prevent engagement opportunities. Maintaining a clean database by removing outdated, fake, or opted-out users will help you stay compliant and optimize your efforts. Lookup helps by confirming phone number ownership and checking for recent changes in consent or SIM cards associated with the phone number.

Data packages to make sure you are contacting the right person:

• Caller Name
• Reassigned Number
• Identity Match
• SIM Swap

Reason #3: Improve deliverability and overall reduce costs

Enhancing deliverability is key to optimizing costs. Sending communications to the wrong person leads to unnecessary expenses, affecting metrics like acquisition costs, cost per message, and potential fines for contacting without consent. Lookup helps by indicating if a phone number can receive your message, based on its type, format, current consent status, and ownership verification. As an example, Reddit has been able to make sure one-time passcodes (OTP) codes are delivered to phone numbers that can actually receive a text using Lookup Line Type Intelligence.

Data packages to improve deliverability and reduce costs:

• Formatting and Validation (free!)
• Line Type Intelligence
• Reassigned Number
• Identity Match

Reason #4: Protect against fraud

Fraud is constantly changing, and phone numbers can offer crucial insights to combat it. Ignoring fraud signals can lead to significant costs, loss of brand credibility, and diminished user loyalty. Lookup can detect if a phone number has been compromised by a SIM swap attack or linked to SMS Pumping Fraud. Businesses can use these signals to take appropriate action, either as a standalone measure or integrated into their decision-making processes. Companies like Persona have been able to heavily reduce their exposure to SMS Pumping in the last six months by using it.

Data packages to protect against fraud:

• SMS Pumping Risk Score
• SIM Swap
• Call Forwarding
• Line Type Intelligence
• Line Status

Reason #5: Improve user experience with background actions

User experience is crucial for every digital business and can be what sets top companies apart. A superior user experience boosts conversion rates, loyalty, and revenue and can set your company apart from your competitors. Lookup offers products and features that operate in the background without disrupting the user experience, whether users are signing up, requesting an OTP code, or initiating a high-value transaction. It performs fast API requests to validate phone number ownership and other checks seamlessly, ensuring a smooth and efficient user experience.

Data packages to improve user experience:

• Identity Match
• Identity Pre-fill
• Line Type Intelligence
• Reassigned Number
• SIM Swap
