Guide · Call Tracking
The tracking number itself is a line item — and it runs $1 to $4.50 a month before a single call connects
Four call-tracking vendors publish a flat monthly fee per provisioned number; at keyword-level scale that recurring charge, not the base plan, is what moves your bill.
Most call-tracking comparisons stop at the base plan. But a tracking number is a phone number a carrier provisions and rents to you every month, so it carries its own recurring fee — separate from the base subscription and separate from the per-minute charges your calls rack up. For a business running one or two numbers, that fee is a rounding error. For anyone doing keyword-level or campaign-level tracking — where the whole point is to spin up a fresh number per ad group, per landing page, per source — it becomes the line item that dominates the bill.
Across the vendors that publish a per-number rate, the spread is 4.5x: from Dialics at $1.00/mo per local number to WildJar at $4.50/mo on its Starter plan.
Who publishes a per-number fee, and what it is
Four vendors in our dataset state an explicit flat monthly charge per provisioned number:
| Vendor | Plan | Per-number / mo | Base / mo |
|---|---|---|---|
| Dialics | Pay As You Go | $1.00 (local) | $0 |
| Convirza | Agency | $1.00 | $149 |
| Ringba | Professional | $2.00 (local) | $297 |
| Convirza | Starter | $3.00 | $29 |
| Ringba | Business | $3.00 (local) | $147 |
| WildJar | Agency | $4.00 | $89 |
| WildJar | Starter | $4.50 | $39 |
Two patterns jump out. First, the per-number fee often moves opposite to the base plan: Convirza’s cheaper Starter tier ($29) charges $3.00/number while its pricier Agency tier ($149) drops that to $1.00 — a three-fold difference that only matters at volume. Ringba does the same, $3.00 on Business falling to $2.00 on Professional. The upgrade isn’t just buying features; it’s buying a cheaper number rate.
Second, WildJar is the most expensive per number on every published tier — $4.50 on Starter, $4.00 on Agency — and it publishes no bundled numbers to offset that. Dialics sits at the other end at $1.00 for a local number (its toll-free numbers run $2.00/mo), and because Dialics has no monthly base at all — it’s pure pay-as-you-go — the number fee is most of the fixed cost.
Why the spread dominates keyword-level tracking
Run the arithmetic at the volume this fee is built for. Suppose you provision 30 tracking numbers to attribute calls down to the keyword:
- On Dialics, that’s 30 × $1.00 = $30/mo in number rent, on top of a $0 base.
- On WildJar Starter, the same 30 numbers cost 30 × $4.50 = $135/mo — more than three times the vendor’s own $39 base plan.
The base subscription you compared in the brochure is now the smaller half of the bill. At 30 numbers WildJar’s number rent ($135) eclipses its base ($39); at Dialics the number rent ($30) is the entire fixed outlay. This is the trap in ranking these tools by sticker price: a $39 plan with $4.50 numbers is structurally more expensive at scale than a $0 plan with $1.00 numbers.
The bundlers play a different game
Not every vendor itemizes numbers. CallRail’s entry Lead Tracking plan ($50/mo) bundles 5 local tracking numbers and 250 local minutes into the base, then meters beyond that at a platform-wide $0.045/min — it does not publish a flat per-extra-number rate at all. That’s a genuinely different model: for a business that needs a handful of numbers, five-in-the-box can beat a low base with a per-number tax. The itemized vendors only pull ahead once your number count climbs past what any bundle includes.
How to read this
If your tracking strategy is a few numbers — one per location, one per channel — the per-number fee is noise; pick on features and base price, and a bundler like CallRail may quietly include everything you need. The moment your strategy is granular attribution, invert the question: a number rate of $4.50 versus $1.00 is a 4.5x multiplier on your fastest-growing cost. At that point the cheapest base plan and the cheapest tracking program are rarely the same vendor, and the per-number column — not the headline price — is the one to negotiate. As always, these are published rates captured from each vendor’s pricing page; metered per-minute and recording charges sit on top, and we publish the source behind every figure.
