A telephone country code is customarily written beginning with a plus sign, as in +1 for North America (USA, Canada, etc.), +44 for the United Kingdom, or +679 for Fiji.
The plus sign means "insert your international access prefix here." Since many countries use different prefixes, it is least confusing to write the international number with the country code beginning with the plus sign, rather than writing, for example, 00966, which could be Saudi Arabia (+966, with 00 as the access prefix) or Thailand (+66, with 009 as the access prefix).
00 is not a telephone country code, nor is it part of a country code. Telephone country codes never begin with zero. Many countries use 00 as an international access prefix (although many countries use various other prefixes) before dialing a country code. For example, to call Fiji (country code +679) from countries that use 00 as the international access prefix, you would dial 00 679.Also, mobile numbers use the same telephone country codes as landlines, with the exception of special global service codes like +870 or +881 for satellite phones.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
The country code for Lithuania is +370. Mobile numbers are in the range +370 6. When writing a telephone number in international format, use only the plus sign, digits, and blank spaces, with no parentheses, dashes, dots, slashes, or other punctuation.
+421 is the country code for Slovakia. Substitute your international dialing prefix for the plus sign. Thus, from most of Europe, dial 00 421; from the US and Canada, dial 011-421; from Australia, dial 0011 421.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
Mobile phones in Cuba are in area code +53 5.(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but North America (USA, Canada, etc.) uses 011, and many other countries use different prefixes.)
The '00' is a commonly used international access prefix, but many other countries use different prefixes. The country code is +60, where the plus sign represents "insert your international access prefix here", and the '14' is the start of the area code and number. +60 is Malaysia.
No country has the country code +307. Country code +30 is Greece, but no numbers begin with +30 7.(The plus sign means "insert your international access prefix here."

'00' isn't part of the country code, it is a commonly used international access prefix. However, country code +292 does not exist.Some countries use '002' as an international access prefix, which would leave country code +92, which is Pakistan.(This is why it is confusing and incorrect to include the access prefix with the country code. The country code should be quoted with the plus sign (meaning "insert your international access prefix here") and the one-, two-, or three-digit country code. For example, the United States and Canada are +1, Pakistan is +92, and Ghana is +233.)
Belarus is country code +375.(The plus sign means "insert your international access prefix here."

011 is not a country code, it is the international access prefix for calls from North America (US, Canada, etc.). International numbers should be written with a plus sign before the country code: for example, +44 for the UK, +61 for Australia, or +211 for South Sudan. The plus sign means "insert your international access prefix here"; different countries use different prefixes, such as 011, 00, 0011, or 8•10.
