Is telecommunication one of the main channels of your marketing strategy? Then, you have to be sure about the quality of the tel numbers of your database. Using Phone Validation, a professional, online add-on, you’ll be able to verify your contacts directly in the Google Sheets quickly and easily. 

Having validated, accurate phone numbers, you’ll get such benefits as:

- Increase in lead generation. With quality telephone numbers, you’ll reach out to the right people at the right time and provide them with the right information.

- Money saving. If you use a robotized system to call your clients and need to pay for a certain amount of dialed numbers, it makes sense to verify the data before.

- Optimization of employee work. Using a tool for validating contact numbers, your team members don’t need to investigate contacts manually and can focus more on telemarketing campaigns. 

- Regulation compliance. When you’re doing marketing campaigns via phone, you need to follow specific rules. With a clean client database, you’ll easily comply with telemarketing regulations. 

- Improvement of your marketing strategy. The validator allows you to get to know not only the status of the contact but also its GEO location. Considering this information, you can enhance your marketing campaigns and use a more personalized approach. 


You can verify international and local numbers, cell phones, and landlines. The service analyzes users in the USA, Canada, Germany, France, Italy, Spain, Portugal, Brasil, and Australia. 

The process of inspecting consists of three stages:
- check for validity: a contact has to be in a standard format, includes numbers, starts with country code or existing mobile operator’s code;
- line test: checking the process of calling (all signals during the call, operator’s notifications, etc.);
- database check: inspecting the extended information about the user, e.g. location.


Step 1. Install the add-on from the Google Workplace Marketplace, and it’ll appear in the Add-ons tab in the Google Sheets. 

Step 2. Go to the spreadsheet with the data or create a new Google Sheet and click the Add-ons -> Phone Validation -> Start. 

Step 3. Add the data headers (Phone number and Validation data), and select an appropriate country from the drop-down menu. Work with existing contacts or paste the bulk of numbers to verify in the document. When all settings are done, click the Validate data option and wait a few minutes to get the results.
