6 Best Phone Number Databases for Australia in 2026 (Ranked)
By Kushal Magar · October 12, 2026 · 11 min read
Key Takeaway
A phone number database Australia teams can rely on is judged on local mobile accuracy and clean compliance, not record count. Business numbers sit outside the Do Not Call Register, but sole traders' mobiles may not, and the Privacy Act still governs personal information. Test each provider on a 200 to 500 contact Australian sample, then screen the output before anyone dials.
TL;DR
The best phone number database Australia sales teams can buy is the one whose mobiles actually connect on Australian prospects and whose company records tie back to the ABN, not the one with the biggest global count. Here is the short version.
- Best for filling Australian gaps across sources: SyncGTM, waterfall across 50+ providers
- Best ANZ direct dials: Firmable, from US$55 per user per month billed annually
- Best ABN-linked company data: KnowFirst, from A$120 per month
- Best self-serve lookups: Lusha, public USD pricing from $49.90/mo
- Best if you also dial Europe: Cognism, quote-based, phone-verified mobiles
- Best free-to-start option: Apollo.io, free plan available
Phone Number Database Australia: DNCR, Calling Hours and the Privacy Act
Australian outbound runs on three rules: what the Do Not Call Register covers, when the standard lets you ring, and how the Privacy Act treats a person's number. Know them before you load a list into a dialer.
Does the Do Not Call Register cover B2B numbers?
The Do Not Call Register Act 2006 is administered by the ACMA, and its Do Not Call Register page sets out which numbers can be listed. Business numbers cannot be added, and a number used for both work and home qualifies only if private use is more than half of its use.
In practice that leaves a gap. A sole trader or contractor who runs everything off one mobile may have registered it, so a B2B mobile list still needs a washing step before you dial.
Calling hours under the industry standard
Hours come from the Telecommunications (Telemarketing and Research Calls) Industry Standard 2017, not from the register. The ACMA's telemarketing guidance lists weekday calls from 9am to 8pm, Saturday from 9am to 5pm and no Sunday calls. The standard also requires callers to identify themselves and end a call when asked. Confirm the current table on the ACMA site, because instruments get amended.
Privacy Act 1988 and the APPs
A mobile number tied to a named person is personal information. The OAIC's Australian Privacy Principles quick reference says APP 7 allows personal information to be used for direct marketing only if certain conditions are met, and APP 5 requires notice at collection.
Whether the Act binds you depends on your size and activity, so check with an adviser. Either way, log where each number came from and honour opt-outs. This is general information, not legal advice.
ABN-linked data and AU mobile formats
Australian mobiles start with 04 and run to 10 digits, which the ACMA sets in its numbering plan. Store them as +614xxxxxxxx so dialers and register checks match. Pair each contact with the company's ABN where you can, since it separates a live employer from a deregistered shell. For a wider list of local tools, see our guide to the best B2B databases for Australia.
1. SyncGTM
SyncGTM is a GTM data platform best suited for Australian teams whose first-choice database keeps returning blanks on mobile numbers. It waterfalls phone enrichment across 50+ providers, so when one source has no number for an Australian contact, the next is tried.
That matters locally because no single source covers every Australian company size. A waterfall lifts match rate on the contacts a single database misses, and results sync natively to Salesforce, HubSpot, Pipedrive, Attio and Close.
SyncGTM does not replace your Do Not Call Register wash, so run its output through one before dialing. See how the approach works in our waterfall phone finder roundup, or estimate spend with the credits estimator.
Pros
- Queries 50+ providers in sequence for higher Australian match rates
- Native sync to Salesforce, HubSpot, Pipedrive, Attio and Close
- Works beside a local database such as Firmable to fill its gaps
- Free tier to test on your own Australian list
Cons
- It enriches contacts you specify rather than selling a downloadable static list
- Do Not Call Register washing is a separate step you need to run
Best for: Australian outbound teams that need mobiles for contacts a single database misses.
Pricing: Free tier available. See the pricing page for current plans.
2. Firmable
Firmable is an ANZ-first sales data platform best suited for Australian outbound teams that live on direct dials and want local sourcing behind them.
Firmable's pricing page lists mobile numbers and work emails as core people data, and every unlocked profile includes all available contact details. Profiles act as credits, so one unlock or export uses one profile from your yearly allowance.
Our own Firmable review found its local sourcing gives higher mobile hit rates than Apollo, ZoomInfo or Lusha on Australian contacts. Treat that as an observation from one stack, then confirm it on your own list during the 14-day trial.
Pros
- Built for Australia and New Zealand first, not appended to a global database
- Mobiles and work emails come with each unlocked profile
- Published pricing and a trial with 25 profiles
Cons
- Prices on the global page are in US dollars, not AUD
- Yearly profile allowances (1,200 on Individual) cap heavy calling
Best for: Australian and New Zealand SDR teams that want local direct dials from one vendor.
Pricing: Individual US$55 per user per month billed annually (US$110 monthly), Small Teams US$75, Teams Pro US$110, Enterprise US$170. Check Firmable's Australian pricing page for AUD.

3. KnowFirst
KnowFirst is an Australia and New Zealand business database best suited for teams that want company records tied to official registers before they chase a phone number.
KnowFirst builds its backbone on ABN, ACN and GST status in Australia and the NZBN in New Zealand. That makes it the strongest pick here for verifying that a business is real, active and registered before anyone dials.
Searching is free, which lets you test coverage for your ICP before spending a credit. It is an Australia and New Zealand tool only, so international prospecting needs a second source.
Pros
- ABN, ACN and GST status give a registry-backed company record
- Free search and a free plan of 20 credits
- Pricing quoted in AUD and published
Cons
- Coverage stops at Australia and New Zealand
- Phone coverage for individual mobiles should be tested on your own sample
Best for: Teams that segment by ABN, entity type or GST status and then pull contacts.
Pricing: Free plan (20 credits). Starter A$120/mo (200 credits), Growth A$216/mo (600), Professional A$600/mo (2,000); annual billing is half price. Prices include GST.

4. Lusha
Lusha is a self-serve contact lookup tool best suited for individual reps who want a number from a LinkedIn profile in a few clicks.
Lusha publishes its prices in US dollars. A phone reveal costs 5 credits against 1 credit for a verified email, so a Starter plan of 400 credits reveals about 80 numbers a month.
Its pricing page says nothing about Australian coverage or the Do Not Call Register. Run a local sample before you assume the mobile hit rate suits an Australian ICP.
Pros
- Public pricing with a free plan of 40 credits a month
- Quick browser-based lookups for ad hoc prospecting
- Easy to trial alongside a local tool
Cons
- Phone numbers cost 5 credits each, so calling volume gets expensive
- No ABN or Australian register data
Best for: Solo reps and small teams doing light mobile lookups in Australia.
Pricing: Free (40 credits/mo). Starter $49.90/mo (400 credits), Pro $69.90/mo (600), Premium $399.90/mo (3,400). USD, cheaper billed annually.

5. Cognism
Cognism is a phone-verified contact database best suited for teams selling across Europe that also want some Australian mobiles.
Cognism's pricing page says verified mobiles are phone-verified to lift connect rates, and that on-demand mobile verification arrives on the Pro plan. One credit reveals one contact.
The page describes European B2B data and does not name Australia, so do not assume a strong AU mobile fill. If Australia is your main market, test Cognism against a local vendor on the same sample.
Pros
- Phone-verified mobiles are central to the product
- Pro plan adds on-demand mobile verification
- Good fit if the same team also dials Europe
Cons
- Pricing is quote-only, with five seats on each plan
- Australia is not listed as a covered region on the pricing page
Best for: Multi-region teams where Australia is one market among several, with Europe the core.
Pricing: Quote-based (Standard and Pro, five seats each). Check current pricing with Cognism.

6. Apollo.io
Apollo.io is a self-serve prospecting platform best suited for Australian startups that want a free-to-start database with built-in sequencing.
Apollo offers Free, Basic, Professional and Custom plans, with credits pooled across the team and reset each billing cycle. Unused credits expire, so plan around monthly volume.
Its pricing page does not list a mobile allowance for Australia. Use Apollo as a wide net for email and company data, then check its AU mobile hit rate on a sample before building a calling plan on it.
Pros
- Free plan to test Australian coverage at no cost
- Dialer and email sequences in the same product
- Large contact pool for early-stage prospecting
Cons
- AU mobile accuracy varies by role and company size
- Credits expire each cycle and do not roll over
Best for: Australian startups that need volume on a small budget and can verify numbers themselves.
Pricing: Free plan, then Basic, Professional and Custom. Check current pricing on Apollo's site.

Prices come from each vendor's pricing page and change often, so confirm before buying. Only KnowFirst quotes AUD here; others are USD. "None" or "not mentioned" means we found no statement on the page, not that the vendor lacks the feature.
How to Test an Australian Phone Database
Take 300 Australian contacts from your real ICP and run the same list through each trial. Measure how many come back with a mobile or direct dial, not how many records the vendor claims.
- Wash every returned mobile against the Do Not Call Register and note how many drop out
- Dial a sample of 50 inside the permitted hours and log connect rate and wrong-person rate
- Divide plan cost by numbers that survived the wash and connected
That last figure is your real cost per usable number. Credit systems differ, so a vendor charging 5 credits per number needs a bigger plan than its headline price suggests.
How to Choose
If you sell only in Australia and New Zealand, start with Firmable for direct dials and KnowFirst for ABN-backed company data, and trial both on the same sample. If you are one rep on a budget, compare Lusha with its alternatives in our Lusha alternatives guide.
If one vendor keeps missing your Australian contacts, a waterfall such as SyncGTM fills the gaps. Whatever you pick, wash against the register close to dial day. Selling abroad too?
