Quackr review: a rental from $12.99 a week, and three free US numbers behind the 1,000+ claim
★★★★☆ 3.7 / 5更新于 由 SMS ActiveR 团队撰写
一句话结论
Quackr is best for one thing: renting a private phone number in one of eight countries and keeping it for weeks or months, backed by a Trustpilot standing that leads the paid sms category we track. It falls short on flexibility. Rental prices sit high, the free board is thinned out in the countries most people search, and there is no mobile app. Our bottom line: 3.7 out of 5. A fair rental service, but a poor fit if all you want is cheap one-off verification codes.
Quackr strengths: 30 countries and 5+ payment methods
Real SIM phone numbers, not VoIP. Useful for online services that reject virtual number ranges.
One dedicated line for weeks or months, with unlimited codes included on the paid rental.
A documented API and an MCP server for AI agents, so the service can plug into automated flows.
Payments both ways: Visa and Mastercard on the card side, Bitcoin, Ethereum and Tether on the crypto side.
Every paid plan bundles a free private email address on the quackr.id domain, useful when a sign-up asks for both a phone and an email.
Public reputation on Trustpilot is genuinely strong: 4.0 out of 5 across 1,340 reviews on a claimed profile.
Quackr does run a free section of shared phone numbers across 30 countries, and codes do land in the public inbox for anyone on the page to see. It is a real free service, but coverage is thin outside the United Kingdom and the Netherlands. The United States, India, Indonesia, South Korea and Spain each showed only three entries the day we checked. Need free numbers that actually receive codes? Try free SVN numbers.
Quackr pricing: a rental from $12.99 a week, not a price per code
Quackr sits on the higher side for pricing because it sells a rental, not a per-code sms activation. A private United States line costs $12.99 for one week (unlimited codes on that line), $15.99 for one month, $59.99 for six months, or $99.99 for a year. The twelve-month plan is the one the site marks as most popular. If all you need is one verification code and then discard the line, that cost is well above what a pay-per-code service charges.

Quackr 后台实测
Quackr splits the interface in two. The free public board lists a handful of shared phone numbers per country page, with the last digits masked until you open an entry. The paid dashboard is where you pick a country, a plan length and a line to rent. The private inbox then keeps every incoming code for the length of the rental.
如何在 Quackr 上接收验证码
Open quackr.io and pick between a free shared line and a private paid rental.
For the free board, choose a country flag. The site lists 30 countries, but many hold only one or two entries online.
Click a listed entry to reveal the full digits, then paste it into the online service you are signing up for.
Wait on that entry's page and watch the public inbox refresh. Verification codes land in view of anyone else on the same page.
For a private line, create an account, pay for one week to twelve months, and keep that single line for the whole plan.

Coverage spans 30 free countries but only 8 you can buy a number in
Quackr covers 30 countries on the free board but only 8 on the paid side: the United Kingdom, United States, Germany, France, the Netherlands, Sweden, Canada and Australia. The free board is heavily skewed. The United Kingdom and the Netherlands together hold about 62% of the roughly 8,900 phone numbers online, while the United States shows only three free entries, with India, Indonesia, South Korea and Spain looking the same. Ten of the 30 country pages hold exactly one entry, including Australia, Brazil, Mexico, Russia and Thailand.
支付选项
Quackr accepts Visa and Mastercard for cards and Bitcoin, Ethereum and Tether for crypto. Refunds return to the original method, but crypto refunds are paid in USDC on the Ethereum network no matter which coin funded the deposit. Useful to know if you paid in Bitcoin. The refund window itself is narrow. A line that never receives a message has to be reported within 48 hours, the team will try to fix or replace it twice, and only after two failed replacements is a full refund due. Any line that has received a single verification code is treated as used, and from that point neither refund nor exchange is offered.
Quackr 在我们测试中的表现
We reviewed the service the way a buyer would. On 2026-08-11 we opened Quackr's free-numbers catalogue country by country, counted how many phone numbers were live in each of the 30 flags, and compared what the site advertises against what actually loads. We read the paid rental plans, the refund policy in full, and every payment method the checkout accepts. We checked public reputation on Trustpilot and cross-referenced the site's own claims: the free page says 1,000+ entries from 24 countries, the front page says USA, UK and 30 other countries, the menu lists 30. We did not run automated activation attempts against WhatsApp or Google, because the free board is public and any code shown there would already be visible to every other viewer on the page.
我们检查了什么
Counted the free board country by country on 2026-08-11, all 30 pages, from each page's own active-numbers counter.
Read the rental price card for a United States private number at all four terms and checked which countries private numbers are sold for.
Read the refund policy line by line, including the 48-hour window, the two replacement attempts and the point at which a number counts as used.
Checked the product line beyond numbers: the API, the MCP server, the eSIM section and the private email address bundled with a plan.
Read the public Trustpilot profile for the score, the review count and whether it is claimed.
Did not buy a rental and ran no activations, so no delivery rate, success rate or code-arrival time of our own is claimed for Quackr anywhere on this page.

SMS Verification Number 是我们评分最高的选择，所以用作参照列。数据来自我们上面的亲测；竞品的可用性会随时间变化，你的实际结果可能不同。
Real SIM phone numbers rather than VoIP. Better odds against strict online services that stop VoIP ranges.
One dedicated line for weeks or months, with unlimited codes baked in.
Public reputation on Trustpilot is genuinely strong at 4.0 out of 5 across 1,340 reviews.
Fiat and crypto both accepted: Visa, Mastercard, Bitcoin, Ethereum and Tether.
A documented API and an MCP server for AI agents. The service can slot into automated verification flows.
Every paid plan bundles a free email address on the quackr.id domain alongside the rental line.
缺点
Paid coverage is narrow: only 8 countries on rental, against the 30 on the free board.
Prices sit at the high end for anyone who only wants a single verification code. The rental bills you by period, not by delivered sms.
The free board is thinnest where demand is highest. The United States page held three phone numbers, and China, India, Indonesia, South Korea and Spain looked no better.
No mobile app. No Android apk and no iOS build, so the Quackr service runs only in a browser.
Refund rules bite fast: a single received verification code ends the refund window, even though the site itself warns one line may not clear several online services in a row.
The site's own catalogue claims do not line up: the free page advertises 1,000+ phone numbers from 24 countries, the front page says 30 other countries, the menu lists 30. Treat those figures as directional.
Quackr 不适合哪些场景
You only need one throwaway verification code and want to pay only for that code. The rental model overpays for a single sms.
You need a private line in India, Brazil, Russia or Mexico. Those countries live only on the shared free board.
You prefer working from a phone app rather than a browser. Quackr ships no Android apk and no iOS build.
You want one line to clear several online services in a row. The site says openly it cannot guarantee that, and the used-once refund rule leaves the risk on you.
我们测试团队的观察
We counted every country page on Quackr's free board on 2026-08-11 and stopped at about 8,900 entries across all 30 of them. The United Kingdom and the Netherlands together hold about 62% of that, and the United States page, the one most people actually search, showed three phone numbers.

The site's own catalogue claims do not agree. The free page advertises 1,000+ phone numbers from 24 countries, the front page says USA, UK and 30 other countries, and the menu lists 30 in total.

Quackr verdict: narrow paid coverage and a pricey rental, carried by the best reputation in this category
Quackr sits in a narrow niche. The rental service works if you need one dedicated line and plan to keep it for months, especially in the United Kingdom or United States. The free board is another story. The United States page showed three phone numbers, and ten of the 30 country pages held one entry each the day we checked. Trustpilot rates the site 4.0 out of 5 across 1,340 reviews, the strongest public reputation in this category, and that weight is real. For quick one-off codes on a fresh line, this is not the shortest or cheapest sms route. Turnover on the free sms boards is thin, so a code you need in the next minute may never land. If throwaway sms verification is the job, a service with a deeper live pool will finish it faster.
Quackr 是什么？
Quackr is a UK-facing service selling private long-term phone numbers, with a free public inbox of shared phone numbers running alongside. The paid side is a rental. Pick a country from a list of eight, pay for one week to twelve months, and keep the same line with unlimited SMS for the length of the plan. The site also ships a documented API, an MCP server for AI agents, an eSIM section, a carrier lookup tool, and a free private email address on the quackr.id domain with every plan.
Quackr 常见问题
Only if you accept the trade-off. The free page carries a fixed banner warning that everyone on the page sees your codes, so a shared line works fine for throwaway sign-ups but not for anything tied to a real account. For a private inbox on the same online services, the paid rental or a per-code sms service is the right route.
The menu lists 30 countries on the free board and 8 on the paid rental (United Kingdom, United States, Germany, France, the Netherlands, Sweden, Canada, Australia). The site's own pages disagree on the free total. The free page claims 1,000+ entries from 24 countries, so treat catalogue figures as directional.
No. There is no Android apk and no iOS build for Quackr. The site runs only in a browser.
Visa and Mastercard for cards, plus Bitcoin, Ethereum and Tether for crypto. Card refunds return to the original card. Crypto refunds are paid in USDC on the Ethereum network whatever coin funded the deposit.
Yes, but the rules are tight: report the phone number within 48 hours, let the team try to fix or replace it twice, and only after two failed replacements is a full refund due. The moment a single verification code lands on that line, refunds and exchanges end, even though the site itself says one line may not clear several online services in a row.
