Measuring the ROI of traditional ads has long been difficult — unlike digital campaigns that offer instant analytics, static ads like posters and radio spots lack measurable data. Thanks to virtual phone numbers, companies now possess an easy, game-changing solution to understand exactly how their offline campaigns are performing.

Virtual numbers are cloud-based lines that exist without a physical SIM or landline — it forwards calls to multiple endpoints including mobiles, teams, or automated systems. By assigning a distinct virtual number to every ad placement — say one number on a billboard in downtown and another on a radio commercial — you gain clear insight into call volume per ad. You gain factual, measurable insights into your ad performance.
For example, if you run a local service business and place ads in three different newspapers — each advertising channel gets its own dedicated tracking number. At the end of the campaign, you can review call logs and see which newspaper brought in the most leads. Track when calls occur, how long they last, and if they result in actual sales or appointments.
Virtual numbers also work with call recording and voicemail transcription, enabling you to listen to customer interactions and uncover their key concerns. This feedback helps you refine your message for future ads. You might discover that customers respond better to a discount offer mentioned in one ad versus a loyalty program in another.
Another advantage is cost control. Instead of guessing which media outlets are worth the investment — you get undeniable proof of what drives conversions. If a radio spot yields zero leads, shift funds to a higher-converting medium. This turns advertising from a gamble into a data-driven strategy.
Setting up virtual numbers is quick and affordable. Many services allow you to buy and assign numbers through an online dashboard. Toggle numbers on or off with a single click. Certain providers include texting features to capture inbound messages.
