Existing addresses are controlled by central authorities. An address gives a person his/her identity because it puts them on the map, helps them open bank accounts, provides access to e-commerce deliveries, emergency services, and voting. But, shockingly, billions of people still don't have formal addresses today hurting their financial, political & digital inclusion.

Smart addresses are designed to augment existing addresses - not replace them. Where street addresses don't exist, smart addresses are readily available. Where street addresses are not accurate, smart addresses are guaranteed to be accurate because they are GPS-based.

๐Ÿ’ก Smart addresses are decentralized. That means anyone anywhere can get an address anytime without having to wait for a central authority to issue a formal address!


Smart addresses are designed to look like real addresses - not random words or confusing codes.

Most importantly, unlike others, smart addresses are sequentially numbered like real addresses.

  1. ๐Ÿ’ฏ Two in One!
    Smart addresses combine the best of both worlds. On the surface, a smart address looks like a simple street address. But, under the hood, it is nothing but a geocode.

    Smart Address Breakdown
    @7215 BRONZE CASTLE 20
    PARIS +25U53
    (10x10 blocklets =
    1 Block)
    (80x80 blocks =
    1 Superblock)
    (20x20 superblocks =
    1 Megablock)
    (480x240 megablocks =
    Entire world)
    ๐Ÿ’ก The megablock codes, aka +FIVEs, are optional but recommended for guaranteed accuracy. The nested geocodes are computed using a simple rule of "start at southwest corner, go east & then north". Only the first letters, e.g., B & C, of the 4-km superblock are the actual geocodes. And so, BIG CASTLE, BLUE CAMP, BRONZE CASTLE, etc. are all considered equivalent.
  2. ๐Ÿ“Œ Last-meter Accuracy
    Smart addresses accurately pinpoint locations down to the last 5 meters worldwide similar to your smartphone GPS[]. And, they also support more precision if desired.

    ๐Ÿ’ก The 5-meter precision is often enough to locate houses, buildings, landmarks, etc. Smart addresses can also make use of apartment, unit, suite numbers, etc. for improved accuracy or vertical resolution.
  3. ๐Ÿ“ Location Codes
    An atCode is just a condensed smart address in alphanumeric form. AtCodes are last-meter-friendly global location codes. And so, they can be used as global zip/pin codes!

    @7215 BRONZE CASTLE 20
    PARIS +25U53
    A smart address
    Corresponding atCode
    ๐Ÿ’ก AtCodes get you to the last meter worldwide! You can further shorten them to codes such as @7215, @7215BC, etc. You can augment traditional addresses with atCodes to modernize & optimize logistics planning.
  4. ๐ŸŒ Global Area Codes
    The megablock identifiers, aka +FIVE codes, act like global area codes. They are similar to postal codes for unaddressed places. And, they follow a simple 5-character format of +DDADD worldwide. You can use just the first line of a smart address, aka megablock handle, as a local address within your +FIVE area.
    ๐Ÿ’ก San Francisco's megablock is about 10 times the size of the entire city (see above). Therefore, the whole city has just one +FIVE code. And, so do most cities. Often, many of the top-10[] megacities in the world have no more than four. The first two digits of the +FIVEs are the longitude bands. And, the middle letters are the latitude bands.
  5. โœ๏ธ Localizable
    Smart addresses can be localized to various country-specific address formats[] and even local languages. Currently, US, France, Germany, India, and Spain address formats are supported.

    @ISLA ROSA, 1234, 56
    Madrid, Spain
    Indian-style smart address
    @2438 เค—เคพเค‚เคงเฅ€ เคชเฅ‚เคฐเคพ 1356
    Mumbai, India

    ๐Ÿ’ก For international smart addresses, just add the +FIVE in the end!
  6. ๐Ÿงฉ Interoperable
    Smart addresses are designed to coexist with real addresses - not replace them. And so, you can use apartment, unit, or suite numbers if available. In fact, you can even use existing zip/pin/postal codes for interoperability.

    ๐Ÿ‡บ๐Ÿ‡ธ US-interoperable

    @1234 SUPER BLOCK APT 101
    City, State, ZIP

    ๐Ÿ’ก Smart addresses can be made interoperable with APO, DPO, & FPO mailing addresses too.[]
  7. ๐ŸŽจ Customizable
    Each smart address can be customized in million+ ways. Customized addresses can convey physical, historical, cultural attributes of places, people, countries, and even your own personal touch. All you have to do is just keep the first letters of the superblock names unchanged.

    ๐ŸŽจ A landmark-based
    @7215 BIG CASTLE 20
    Paris, France
    ๐Ÿ‘ค A user-based
    @7215 BRAAVOS CORNER 20
    Paris, France[]
    ๐Ÿ’ก Just keep the first letters of the superblock the same when customizing a smart address!
  8. ๐Ÿฆพ Resilient
    Smart addresses tolerate incorrect/missing components. For instance, they work just fine without town/city names. In fact, they work even without the other components too but with reduced precision.
    Without town/city
    @7215 BRONZE CASTLE 20
    โœ”๏ธ Still works globally with 5 m precision.
    Without blocklet #
    PARIS +25U53
    โœ”๏ธ Works globally with 50 m precision.
    Without block #
    PARIS +25U53
    โœ”๏ธ Works globally with 4 km precision.
    Without first line
    PARIS +25U53
    โœ”๏ธ Works globally with 80 km precision.
    ๐Ÿ’ก In fact, just @7215 BRONZE CASTLE 20 also works with 5-meter precision but only locally within the same +FIVE area. The town/city name in a smart address is optional but recommended for redundancy to recover from +FIVE errors.
  9. ๏ผ  Personalized One-liners
    The first line of a smart address works as a local address within your megablock. For instance, @101 GOLD FALL 51 or any customized equivalent, can give you 5-meter fix in single-megablock cities such as New York City, Tokyo, Melbourne, etc. And, you can even use just @101 GOLD FALL (without the blocklet) for 50-meter fix!

    A megablock handle gives you a 5-meter location fix anywhere within your megablock!

    ๐Ÿ’ก There are 64M unique handles covering one single megablock. The handles are reused in neighboring megablocks. But you can personalize them in million+ ways to your liking. You can use the megablock handles pointing to your apartment gate, beach, park, etc. for hosting events, meetups, pizza delivery, Instacart, GrubHub, Uber, or other local services. Just add your +FIVE to convert your local handle to a global address!
  10. โฌ…๏ธ Future-proof
    Ignoring the plate tectonic effects[], smart addresses are future-proof for centuries. Because they are built on top of the GPS technology, smart addresses point to the same locations despite town/city/locality name changes[] or zip/pin/postal code changes[]. Now, that's a win-win for postal offices, municipalities, businesses, and you.

    @1042 NEW HILL 95
    Waterloo +11S09
    A smart address
    with old city name
    @1042 NEW HILL 95
    Austin +11S09
    A smart address
    with new city name
    The two smart addresses above point to one and the same location in the city of Austin that was once known as Waterloo - no database updates required!

    ๐Ÿ’ก Plate tectonics: Australia moves at a brisk pace of 2.7 inches northward every year while North America moves at 1 inch per year. So, a smart address will have an "off-by-one" (i.e, 5 m) error after 75 years in Australia and 200 years in the US.
  11. ๐Ÿ•™ What time is it?
    Smart addresses encode not only space but also time. And so, you can even estimate the time difference between any two addresses just from the first two digits of the +FIVEs (i.e., the longitude bands). For example,


    ๐Ÿ’ก The actual time difference between Paris and San Francisco is 9 hours.
  12. ๐ŸŒ Offline-friendly
    Smart addresses work offline. There are no complex hashes or closed database lookups. All you need are just your GPS coordinates and a calculator.

    ๐Ÿ’ก You can even encode & decode smart addresses with just pen and paper.
  13. ๐Ÿฆบ Search & Rescue
    Smart addresses will be helpful for search & rescue operations too. For example, signage, markers, and offline/printed maps can be made available in unaddressed places such as national parks, trails, off-trails, etc., to help people in emergencies.

    ๐Ÿ’ก You can use our app offline too. Just make sure it's in your browser cache.
  14. ๐Ÿ“ฆ Worldwide Deliverability
    A bad address shouldn't mean an undeliverable package. And, no address shouldn't mean no deliveries. Smart addresses are delivery-friendly because they are standardized, less error-prone, resilient to typos for guaranteed deliveries worldwide. In addition, smart addresses will enable e-commerce, drone delivery, and shipping companies can deliver to the next billion people & next trillion people thanks to our game-changing addressing solution.
