Yes, You can approximate a timezone from an address using a Virtual Column in AppSheet, but since AppSheet doesn't support real-time geographic timezone APIs directly, you'll need to use a lookup-based workaround or a combination of address parts. Here's how you can do it depending on your setup:
Option 1: State-to-Timezone Mapping (Best for TCPA)
This is the most AppSheet-native solution and works for most TCPA scenarios.
Step 1: Create a Timezone Reference Table
Create a table like this (you can use a Google Sheet):
Step 2: Extract State from the Address
If you're using AppSheetโs address fields, you may need to separate the state into its own column or use a text formula to extract it:
RIGHT([Address], ๐ // crude way to extract "CA 90210" from the end
Or better: Use a separate [State] column in your form/data input.

Step 3: Create a Virtual Column for Timezone
Add a Virtual Column with this formula:
LOOKUP([State], "Timezones", "State Code", "Timezone")
Replace "Timezones" with the actual name of your reference table.
Option 2: ZIP Code-to-Timezone (More Precise but More Setup)
Use a ZIP-to-timezone reference table (you can find public datasets online). Then:
Extract the ZIP code from the address
Create a ZipTimezones table with ZIPs and corresponding timezones
Use:
LOOKUP([ZipCode], "ZipTimezones", "ZipCode", "Timezone")
Option 3: Manual Timezone Field (Quick TCPA Compliance)
Add a dropdown field [Timezone] with options like: Eastern, Central, Mountain, Pacific. Have your team or Ftomation select it during client intake.
