Recently, some friends advice, currently on the market there is no 11-bit card number things together, medium shot yuan was linked to reports, the first IOT card number is 11, can be a voice card things together, there have been 13 substituted card number, we have now found that this was rarely seen with the card.
Things card is basically why 13-bit?
13 card currently on the market occupies 99% of the market, 11 card number has slowly been replaced, According to reports, the main reason is the existence of the phenomenon of unstable, easily dropped, for customer groups use it if the use of the Internet of Things the way cards appear cassette or interruption, then it may have skewed the data, etc., so the card selection of things when we must choose stability relatively strong, which is the 13 numbers instead of 11 things card numbers one of the important reasons.
11 is a personal phone number on the card as well as traffic, currently only for individuals, (informal a person's identity card only real-name port 5, more than just not real name, network 11 virtual phone cards, currently does not require real names, are not regular operation, use, may face the situation does not take any time, many companies have encountered similar 11 card use experience);
13 operators in accordance with national interconnection of all things grand plan customized industrial-grade corporate Things cards, 13 cards in addition to the things the phone can not be placed outside the pure Internet traffic can be placed on all smart devices for data transmission currently 13 enterprises of things real name card application form by the enterprise, a port to achieve a corporate system account, once the real-name business success in the future card not required to provide documents and background can submit unlimited number card.
No matter which segment associated card?
In the early stages of Things concept card is not mature enough when the section number and cell phone number with the card segment no matter the differences, with the later things getting better card technology, application cards more and more things, things card therefore stressed up, in order to achieve the interconnection of all things, under the Ministry of Industry indication, the three major carriers 145 (China Unicom), 147 (mobile), 149 (telecommunications) as the exclusive card number was linked segment. But now things have already received national attention, has also become a carrier's carrier gap, its exclusive section number and make some changes.
Last year, under the guidance of the Ministry of Industry, paragraph number of things cards by 11 before rose to 13, in a few years to the Ministry of Industry and distribution segment number again, as follows:
1,17400 No. 17405 - segment? - Use: China Telecom Corporation; Uses: satellite mobile communications business segment dedicated number.
